8 Best Excel Alternatives in 2026 (Free & AI Options)
Excel still runs the world’s finances, but the reasons to look elsewhere keep piling up in 2026. On July 1, 2026, Microsoft raised commercial Microsoft 365 pricing across Business, Enterprise, and Frontline plans — increases that run anywhere from 0% to 43%, with the company framing the hike as the cost of bundling Copilot Chat and AI agents into every suite. For teams that just wanted a spreadsheet, that’s an AI tax on a tool they already owned.
At the same time, the “modern AI spreadsheet” category is consolidating fast — Rows, a popular AI-native option, was acquired by Superhuman (Grammarly’s parent) and shut down on May 31, 2026. So the real question isn’t just “what’s cheaper than Excel,” it’s “what’s cheap, stable, and built for how I actually work.” Here are the eight alternatives worth switching to in 2026, from free desktop clones to AI-native grids.
1. Google Sheets
The default free cloud spreadsheet, and the one most Excel refugees land on first.
What makes it different from Excel: Sheets was collaborative from day one — real-time co-editing, comments, and version history are native, not bolted on. It’s free with a personal Google account, runs entirely in the browser on any OS, and now has Gemini built in for formula generation, data cleanup, and “help me analyze this” prompts. Heavy financial modelers will hit its limits on very large workbooks, but for 90% of everyday spreadsheet work it’s a genuine one-to-one replacement. If you’re weighing the two directly, we broke it down in Google Sheets vs Excel.
Best for: Teams and individuals who want free, collaborative spreadsheets with AI baked in.
Pricing: Free with a Google account; Workspace plans from $7/user/month add admin controls and storage
2. LibreOffice Calc
The most complete free desktop clone of Excel, fully offline and open source.
What makes it different from Excel: Calc is the closest thing to “Excel without the subscription” — no account, no cloud, no telemetry, and no per-seat fee, ever. The current LibreOffice 26.2 (released February 2026) matched Excel’s grid at 1,048,576 rows by 16,384 columns and improved clipboard fidelity with Excel. It reads and writes .xlsx, supports macros, pivot tables, and Solver, and runs on Windows, Mac, and Linux.
Best for: Anyone who wants Excel’s depth on the desktop with zero cost and zero lock-in.
Pricing: Free and open source
3. ONLYOFFICE
A free desktop suite whose spreadsheet editor prioritizes near-perfect Microsoft file fidelity.
What makes it different from Excel: Where LibreOffice occasionally mangles complex Excel formatting, ONLYOFFICE was built around the Office Open XML format, so .xlsx files tend to open looking exactly as they did in Excel. The desktop editors are free with no row limits or feature gates, run on all three platforms offline, and there’s a self-hostable server version for teams that want private collaboration.
Best for: Users who exchange complex .xlsx files with Excel colleagues and can’t afford formatting drift.
Pricing: Free desktop editors; self-hosted and cloud collaboration plans available
4. Apple Numbers
Free on every Apple device, and unusually good at spreadsheets that need to look presentable.
What makes it different from Excel: Numbers flips the grid model — you start with a blank canvas and drop tables, charts, and images anywhere, so a finished sheet reads more like a report than a wall of cells. It’s free with any Apple ID, syncs across Mac, iPhone, and iPad via iCloud, and even runs in a browser on Windows via iCloud.com. It’s weaker on massive datasets and advanced statistical work, but hard to beat for polished, shareable spreadsheets.
Best for: Mac and iPad users who want free, design-forward spreadsheets.
Pricing: Free with an Apple ID
5. WPS Spreadsheet
The free alternative that looks and feels the most like Excel out of the box.
What makes it different from Excel: WPS clones Excel’s ribbon interface so closely that most people need no relearning, and it’s genuinely cross-platform — Windows, Mac, Linux, Android, and iOS. The free tier covers the core spreadsheet work plus templates and PDF tools; the trade-off is occasional ads and upsells nudging you toward the paid tier. Formula and .xlsx compatibility are strong.
Best for: Switchers who want the exact Excel muscle memory without the Microsoft bill.
Pricing: Free tier with ads; WPS Premium around $36/year removes them and adds storage
6. Zoho Sheet
A free, fully cloud-based spreadsheet with a capable AI assistant built in.
What makes it different from Excel: Zoho Sheet is free for individuals and small teams with no artificial row caps on par with Excel’s paid tiers, and its Zia AI handles data cleaning, formatting, pivot-table generation, and chart creation from plain-language prompts. A standout feature scans receipts and printed tables and converts them straight into a sheet. It plugs neatly into the wider Zoho ecosystem if you already use their CRM or Books.
Best for: Cloud-first users who want free collaboration plus a built-in AI assistant.
Pricing: Free for individuals and small teams
7. Airtable
Less a spreadsheet than a database that behaves like one — the pick for people whose Excel files became makeshift apps.
What makes it different from Excel: Airtable treats rows as records and columns as typed fields (attachments, links between tables, dropdowns, formulas), so it handles relational data that would collapse a flat spreadsheet. It adds views (grid, kanban, calendar, gallery), automations, and an interface builder. The catch in 2026: the free plan now caps out at 1,000 records per base and 5 editors, and most active teams outgrow it within a few months, landing on the Team plan at $20/editor/month. See how it stacks up in Airtable vs Excel, or browse the full field of Airtable alternatives.
Best for: Teams tracking projects, inventory, or CRM-style data that has outgrown a flat grid.
Pricing: Free up to 1,000 records per base and 5 editors; Team $20/editor/month (annual)
8. Quadratic
An AI-native spreadsheet that runs Python and SQL directly inside the cells.
What makes it different from Excel: Quadratic is built for analysts who hit the ceiling of formulas — you can write Python (with pandas, numpy, and any library) or SQL in a cell, pull live data from a production database, transform it, and drop the result back onto the grid your team interacts with normally. Its AI writes that code from natural-language prompts. It’s overkill for a budget tracker, but for data work Excel forces into VBA or a separate notebook, it’s a genuinely different tool.
Best for: Data analysts and engineers who want code and AI natively inside a spreadsheet.
Pricing: Free tier with limited compute; Pro from $18/user/month
Whichever spreadsheet you land on, Carly can hook right in — native integrations for Microsoft Excel, Google Sheets, and Airtable, plus bring-your-own API key for anything else.

FAQ
What is the best free alternative to Excel? For most people, Google Sheets — it’s free, collaborative, and has Gemini AI built in. If you need a true offline desktop app, LibreOffice Calc or ONLYOFFICE are fully free with no row limits or accounts.
Is there an Excel alternative that opens .xlsx files without breaking the formatting?
ONLYOFFICE has the strongest Microsoft file fidelity because it’s built around the same Office Open XML format Excel uses. LibreOffice Calc and WPS Spreadsheet also read and write .xlsx, though very complex files can shift slightly.
Which Excel alternative is best for large or relational data? Airtable if your data is relational (linked tables, typed fields, multiple views), or Quadratic if you want to run Python and SQL against large datasets directly in the grid. Both go well beyond what a flat spreadsheet handles.
Do I still need Excel if I switch?
Rarely. The main friction is exchanging macro-heavy or heavily formatted .xlsx files with Excel-only colleagues. If your spreadsheets are the source of a lot of manual follow-up work, an AI personal assistant that reads your data and acts on it can remove the reason you were living in the spreadsheet at all.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
