Spreadsheets you can trust.
Deterministic calculation, verifiable outputs, and custom functions
that are part of the proof.
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.
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.

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.
AI, without losing the plot
AI can help you write formulas, summarize changes, and explain complex sheets — without hiding what happened or mutating your data behind your back.
Every AI-assisted change is:
- Clearly marked as AI-generated
- Fully inspectable (what changed, where, and why)
- Reversible with standard undo
- Auditable alongside human edits
Ask AI for help. Keep humans accountable.
No auto-edits. No silent rewrites. No mystery numbers.
Ask AI for formulas
Describe what you want. Insert only after review.
Explain differences
See what changed — with optional AI summaries.
Provenance-aware history
Always know if a change came from a person or AI.
AI assists. You stay in control.
