AI Matrx Workbooks

Spreadsheets that travel with the rest of your work.

Lossless XLSX, multi-sheet, formulas, realtime editing, history. Workbooks live next to your chats, agents, and tasks — the numbers stay the same, the surface around them gets a lot smarter.

Start a Workbook Free See what it does

Excel-grade math, browser-grade collaboration

Five capabilities under every workbook — lossless XLSX, real formulas, realtime, import/export, autosave + snapshots.

Lossless XLSX, in your browser

Multi-sheet workbooks, formulas, conditional formatting, frozen rows — everything that survives the round-trip from Excel intact.

Formulas that actually compute

SUM, VLOOKUP, IF, INDEX/MATCH — the spreadsheet primitives you already know, recomputed live across sheets and references.

Realtime, multi-user editing

Share with a colleague, see their cursor, watch edits flow. Permission-aware — your finance sheet stays out of the wrong hands.

Import / export anything

Drop an XLSX or CSV in; export back out without losing structure. Round-trip works — keep using Excel where it makes sense.

Autosave + snapshots

Every edit saved. Pin named snapshots before risky changes; roll back to any prior state from the version history.

How it works

From an empty sheet (or an imported XLSX) to a shared, live workbook in three steps.

Create or import

Blank workbook, template, or drag in an existing XLSX / CSV. Spin-up is instant; nothing to install.

Work like a spreadsheet

Multi-sheet tabs, formulas across cells and sheets, formatting, freeze panes — the familiar surface, just always synced.

Share, hand off, ship

Share with your team, an agent, or an external collaborator. Export back to XLSX for stakeholders who still live in Excel.

Workbook surfaces

Build, import, collaborate, ship — every spreadsheet flow in one place.
