A free, open source spreadsheet
built for the AI era.
Open your files, inspect the formulas, and let an AI agent work in the sheet with you.
From raw data to work you can trust
Start with your files
- Open Excel, CSV, and ODS exports
- Keep editing and export your results
Make the data usable
- Clean, split, and deduplicate with previews
- Inspect formulas and trace their inputs
Bring your agent
- Connect an MCP agent to the desktop app
- Watch edits live and undo each batch
AI agents + VisiGrid desktop
See what your AI did. Keep working on it.
A table in a chat is a starting point. In VisiGrid, you can edit the values, inspect the formulas, and let a compatible MCP agent work alongside you.
-
01
Connect your agent
Use VisiGrid’s MCP server to give a compatible agent access to your desktop workbook. You allow access and can revoke it.
-
02
Watch the work happen
Ask for a table, a formula, or a cleanup. Agent edits appear in the live grid, where you can inspect the cells and correct the result.
-
03
Stay in control
Undo each batch of agent edits. Revision checks prevent an agent from overwriting changes you made since its last read.
Use your own agent. VisiGrid provides the workspace.
Fast is table stakes. Knowing why a number is what it is makes the difference.
When it matters, VisiGrid shows you where numbers come from and what changed — instantly.
Click any cell to see what it depends on and what depends on it.
Don't trust the output. Verify it.
Deterministic recalculation
You control when values update. No silent drift between opens. No ambient state.
Fingerprint & verify
Same inputs + same formulas = same hash. Verify in CI, in audits, in handoffs.
Custom functions are part of the proof
Lua functions run in a sandbox. No macros, no side effects. Your code is included in the fingerprint.
Features
Type to find any action
No hunting through menus. Press one shortcut, type what you want, and do it. Sort, fill, replace, format — everything is searchable.
Edit many cells at once
Select cells that aren't next to each other. Type once, apply everywhere. Change formatting, enter values, or clear — all at once.
Formula help as you type
Suggestions appear as you write. See parameter names, types, and examples. Spot errors before you finish typing.
Name your ranges
Call it Revenue instead of B2:B100. Formulas become readable. Rename safely across your whole workbook.
Jump to any cell or name
Type a cell reference or a name to go there instantly. No scrolling, no clicking.
See where numbers come from
One click shows formula, value, format, and dependencies. The same inspector you saw above — always one keystroke away.
Opens your Excel files
Drag in XLSX, XLS, XLSB, or ODS files. Large files load in the background. See exactly what imported and what needs attention.
Multiple sheets, one file
Organize data across sheets with tabs you can rename, reorder, and jump between instantly.
Themes + custom shortcuts
Pick a theme or build your own. Remap any shortcut. Settings are plain text files you can back up or share.
Optional automation (advanced)
For teams who treat spreadsheets as part of a larger system. Run formulas from the command line, pipe in data, convert formats, and integrate with CI. AI features follow the same philosophy: optional, local-first where possible, and always auditable.
Why people switch
Desktop suites stopped at the ribbon. Cloud spreadsheets stopped at the browser. VisiGrid is a spreadsheet built like a code editor.
