Best Spreadsheet Apps for iPhone: 7 Top Picks for iOS and iPad in 2026

Shopping for the best spreadsheet apps for iPhone is a nicer problem than it used to be. Apple ships a genuinely good spreadsheet app on every iPhone for free, Microsoft’s Excel for iOS is free for phone-sized screens, and Google Sheets brings best-in-class collaboration to your pocket. But “good enough” depends on what you actually do: a freelancer in Canada invoicing clients has different needs from a warehouse manager in Australia checking stock, or a student in India tracking expenses. Some apps mangle xlsx formatting, others nag you into subscriptions, and a few are just document viewers wearing an editor’s clothes. This guide tests the real contenders on iPhone and iPad — xlsx fidelity, CSV import, offline editing, Apple Pencil support, and honest pricing — so you install the right one the first time.

You’ll get a ranked list of the seven best spreadsheet apps for iPhone in 2026, a clear-eyed look at the free options, a comparison of the strongest Excel alternatives on iOS, iPad-specific advice, and practical help with CSV files and formulas. Whether you’re team Apple, team Microsoft, or team “whatever’s free,” you’ll know exactly which app earns your home screen.

What to look for in an iPhone spreadsheet app

iPhones change the spreadsheet equation in two ways: the screen is small, and the ecosystem is opinionated. An app that shines on a 27-inch monitor can feel cramped and fiddly at 6 inches, and Apple’s sandboxed file system means importing files works differently than on Android. Here’s what we scored.

XLSX round-trip fidelity. Open a desktop-made xlsx, edit it on your iPhone, send it back — did anything break? The best spreadsheet apps for iPhone preserve formatting, formulas, and charts through that round trip. Apple Numbers is surprisingly good at this despite not being Excel; Microsoft’s own app is the gold standard by definition.

iCloud and Files integration. On iOS, your spreadsheet app should play nicely with the Files app and iCloud Drive, because that’s where attachments from Mail and Safari downloads land. Apps that make you hunt through proprietary “my documents” silos waste your time every single session.

Touch-first design. Selecting cell ranges, filling formulas down a column, resizing charts — all of it should work with a thumb. Desktop interfaces shrunk to phone size (we’re looking at you, ported office suites) score badly here no matter how powerful their engines are.

Offline capability. iPhones go offline in subways, planes, and rural coverage gaps just like any phone. Your app should open and edit local files without phoning home, then sync later. Cloud-only editing is a non-starter for travel.

Real pricing. Several iOS office apps are “free” the way a casino buffet is free — technically, but you’ll pay at the tables. We flag exactly which features need a subscription, because an app that locks saving behind a paywall isn’t a free app.

The 7 best spreadsheet apps for iPhone, ranked

We tested each app on an iPhone and an iPad with the same gauntlet: a 5,000-row xlsx with formulas and charts, a messy semicolon-delimited CSV, offline editing with Wi-Fi off, and sharing back to a Windows desktop. Scores reflect the iPhone experience first, with iPad notes where they matter.

1. Apple Numbers — free, preinstalled, and better than you think

Here’s the thing most iPhone owners never realize: you already own one of the best iPhone spreadsheet apps. Apple Numbers comes free on every iPhone and iPad, and it’s genuinely good — not “good for a freebie,” just good. It opens xlsx files cleanly, exports back to xlsx without drama, and its chart and table styling is the prettiest in this entire roundup. iCloud sync means a sheet you start on your iPhone is on your Mac before you’ve put the phone down.

Where Numbers concedes ground: no macros, no Power Query, and a formula library that’s broad but shallower than Excel’s. For personal budgets, small-business trackers, event planning, and schoolwork, none of that matters. Our Apple Numbers to Excel guide covers the export workflow in detail if you collaborate with Excel users — the short version is File › Export To › Excel, and it just works.

2. Microsoft Excel — the best Excel app for iPhone and iPad

When xlsx files are your life, install the real thing. Microsoft Excel for iOS is free on iPhone-sized screens for viewing and editing, and it’s the best Excel app for iPhone and iPad by the only metric that counts here: your files look exactly like they do on desktop. PivotTables, conditional formatting, data validation dropdowns — all preserved, all editable.

On iPad, Excel stretches its legs further with a near-desktop ribbon and Apple Pencil support for inking. The catches: it’s a big download, it wants you signed into a Microsoft account, and the full iPad experience (plus premium features) asks for Microsoft 365. For iPhone-only use, though, the free tier covers nearly everything a normal human does with spreadsheets.

3. Google Sheets — the collaboration king

If your spreadsheets are team sports, Google Sheets wins. Real-time multi-user editing, comments, suggested edits, and version history are smoother here than anywhere else, and the iPhone app is a faithful, fast version of the web experience. It’s completely free with no upsells, syncs across every device you own, and imports both xlsx and CSV gracefully.

The trade-offs: you need a Google account, offline mode requires setup per file, and complex xlsx formatting can shift slightly on import. For families splitting expenses, student groups, and distributed teams — especially common across the US, UK, and India where mixed-device households are the norm — Sheets is often the path of least resistance.

4. WPS Office — the full-suite Excel app iOS alternative

WPS Office on iOS is the same pragmatic deal as on Android: a full office suite — spreadsheets, documents, presentations, PDFs — free with ads. As an Excel app iOS alternative, its spreadsheet module apes the desktop Excel ribbon closely and handles xlsx files with impressive fidelity. If you want one app for every Office format and don’t mind the occasional ad, it’s the most capable free suite on iPhone. Our Excel vs WPS Spreadsheet comparison digs into where it matches Excel and where it doesn’t.

5. Zoho Sheet

Zoho Sheet’s iPhone app is a clean, fast spreadsheet editor that’s free for personal use and surprisingly powerful — 350+ functions, data cleaning tools, and the ability to pull live data from web URLs. Its xlsx compatibility is solid, and it plays well in mixed-OS teams since Zoho runs everywhere. It only lands at #5 because most iPhone users will never need what makes it special; but if you’re a data-curious solo operator, it’s a gem.

6. OfficeSuite

OfficeSuite brings its long Android heritage to iOS with a tidy interface and dependable xlsx handling. The free tier covers viewing and basic editing; serious editing wants the Pro subscription. It’s a fine choice if you like its particular feel or need its PDF tools, but the free options above give you more for zero dollars.

7. Polaris Office

Polaris Office rounds out the list with a stylish interface and competent spreadsheet editing backed by its own cloud sync. Like its Android sibling, the free tier is ad-supported with premium features behind a paywall. Worth trying if you’re already in the Polaris ecosystem on other devices; otherwise the top three cover this ground better.

The best free spreadsheet app for iPhone: no-cost winners

Let’s settle the spreadsheet app iPhone free question properly, because “free” on the App Store covers a multitude of sins. Two apps in this guide are free with genuinely no catch: Apple Numbers (preinstalled, no ads, no tiers, full features) and Google Sheets (free with a Google account, every feature included). Microsoft Excel for iOS is free for iPhone editing but reserves premium features and the full iPad experience for Microsoft 365 subscribers. WPS Office is free but ad-supported.

Which free option should you pick? If you live in Apple’s world — iPhone, maybe a Mac or iPad, iCloud for storage — Numbers is the obvious answer. It’s already there, it syncs silently, and its xlsx export keeps Windows colleagues happy. If you collaborate with Android and Windows users, or you want the best real-time co-editing on the planet, Google Sheets is the better free pick despite needing a Google account. And if your files must look pixel-identical to desktop Excel, the free tier of Microsoft Excel for iOS is your safety net — install it alongside your daily driver and open it only when fidelity matters.

Excel app iOS alternatives compared

Searching for an Excel app iOS alternative usually means you want Excel-compatible editing without the Microsoft account, the subscription nagging, or the 500 MB download. Here’s how the alternatives compare on iPhone specifically.

The iOS wrinkle is iCloud integration: Numbers is the only app here that treats iCloud Drive as home turf, which makes it frictionless if your files arrive via Mail or Safari. Google Sheets and Excel prefer their own clouds (Drive and OneDrive), which is fine if you’re already invested there. Our Android spreadsheet app ranking covers the same apps on the other platform — useful reading if your family or team is split across iPhone and Android, since Sheets and Excel are the two that behave identically on both.

iPad: the bigger canvas for serious spreadsheet work

Everything changes with 11 inches of screen. On iPad, spreadsheets stop being “phone tasks” and become real work: building budgets, reviewing reports, editing inventory sheets with a Bluetooth keyboard. Both top picks stretch to fill the canvas, but differently.

Microsoft Excel on iPad is the closest thing to desktop Excel that isn’t desktop Excel. The ribbon expands, multitasking with Slide Over and Split View works properly, and Apple Pencil support lets you ink annotations directly onto sheets — genuinely useful for marking up a report. Note the pricing catch: on larger iPads, Microsoft requires a Microsoft 365 subscription for full editing, unlike the free iPhone tier.

Apple Numbers on iPad remains completely free and feels the most native — drag and drop between apps, Scribble handwriting-to-text in cells, and buttery chart interactions. For reviewing and light editing it’s delightful. For heavy formula work or files that must match desktop Excel cell-for-cell, Excel still wins.

Practical setup if you do real work on iPad: pair it with a keyboard case, keep your files in one cloud (iCloud if you’re Numbers-first, OneDrive if Excel-first), and learn the keyboard shortcuts — Command-arrow keys for jumping to range edges work in both apps and transform the experience. And if a CSV lands in your inbox while you’re on the iPad, Safari plus the free CSV to Excel converter turns it into a clean xlsx in seconds, no app-hopping required.

CSV on iPhone: importing without tears

CSV files and iPhones have a workable but fussy relationship. When someone emails you a CSV or you download one in Safari, it lands in the Files app — and from there you can open it in Numbers, Sheets, or Excel. Apple Numbers’ CSV import is quietly excellent: it sniffs out delimiters (including the semicolons common in European exports) and usually gets the columns right on the first try. Google Sheets’ importer is equally capable once the file is in your Drive.

The failure mode to watch for: a CSV that opens with everything jammed into a single column. That means the app guessed the delimiter wrong. In Numbers, re-import and set the separator manually; in Excel for iOS, use the import options rather than just tapping the file. Or skip the fiddling entirely — run the file through the free CSV to Excel converter in Safari (it works entirely on your device, so sensitive data never uploads), then open the resulting xlsx in whichever app you prefer. The CSV format is standardized in RFC 4180, but real-world exports bend the rules constantly, so a proper conversion step saves more time than fighting import dialogs.

Also mind encodings: CSVs exported from older Windows programs sometimes show garbled text for accented characters. If names look like gibberish after import, the file is probably in a legacy Windows encoding rather than UTF-8 — re-import with a different text encoding selected and the characters snap back.

Formulas and power features on iOS

For everyday formulas, iOS apps are fully capable: SUM, AVERAGE, IF, VLOOKUP, COUNTIF, and date math all behave identically to desktop across Numbers, Excel, and Sheets. The differences emerge with advanced tooling.

Microsoft Excel for iOS has the deepest bench — XLOOKUP, dynamic arrays, and the newest functions work as documented, which matters if you’re editing a model someone built on desktop. Google Sheets brings its exclusives (QUERY, IMPORTDATA, GOOGLEFINANCE) that have no Excel equivalent and are genuinely handy for live data pulls. Apple Numbers covers the mainstream functions with a friendlier formula editor — its function browser with plain-English descriptions is the best learning tool in this roundup for anyone still building formula confidence.

What none of them do well: VBA macros (Excel for iOS won’t run them), Power Query transformations, and very large files — a 100,000-row sheet will chug on any phone. Rule of thumb: build heavy models on a computer, use your iPhone for viewing, data entry, and light edits. If you need to reshape data on the go, Apple’s support guides and in-app help cover the import and formula basics well.

Verdict: the best spreadsheet apps for iPhone in 2026

Here’s the short version. If you own an iPhone, start with Apple Numbers — it’s already installed, it’s free forever, it syncs through iCloud, and its xlsx export keeps the rest of the world happy. Add Google Sheets if you collaborate with non-Apple people or live in Google’s ecosystem. Add Microsoft Excel if your files must match desktop Excel exactly or you do serious work on an iPad. That trio covers every realistic scenario, and the total cost is zero.

WPS Office earns its place if you want one free app for Word, Excel, PowerPoint, and PDFs together; Zoho Sheet if you’re data-curious and like its live-data tricks. For the Android side of the household, our best online Excel tools guide covers browser options that work identically on both platforms — handy when the family group chat can’t agree on an app.
