Spreadsheets for the numbers you already have.
A spreadsheet that works with all of your operational data inside Calisto Pro. Pull a live table onto a tab, or import the file you already have. Read a row back the other way and it becomes a real invoice.
The Spreadsheet App for Your Own Numbers
Formulas and live tables on one tab, and the file you already have imported whole.
Editor
A formula engine with dependency tracking and autosave.
Create & Import
Start blank, from XLSX or CSV, or from a prompt.
AI Actions
Formula generation, column fill, and questions on your data.
Pivot Tables & Charts
Summarise, chart, both in a side panel.
Live Data
Pull live tables from Ledger and Catalog onto a tab.
Downstream
A row becomes a real invoice or a real task.
Governance
Columns and tabs redacted per member, server-side.
Publish
A read-only link anyone can open, with permissions.
Export & Versioning
XLSX, CSV, PDF, and cell-by-cell version comparison.

Type a formula. Watch every dependent cell catch up.
Calisto's own spreadsheet, written from the grid up. The engine knows which cells depend on which, so one edit recalculates exactly what it should and nothing more.
- Change the tax in B1 and the four cells that read it recalculate. Nothing else does.
- Amounts arrive as raw numbers, so your own account currency formatting applies.
Only the rows on screen are drawn, so a long sheet keeps scrolling instead of stalling. Keep as many tabs in one workbook as the work needs.
Start blank, start from a file, or start from a prompt.
Bring in an XLSX or a CSV and keep working, describe what you need and edit what comes back, or open a starter.
A new workbook opens immediately with autosave on. One sheet, 100 rows, 26 columns.
Upload by drag-and-drop or file picker, up to 50 MB. Leading-zero codes stay text, and imported formulas re-evaluate under the Calisto engine.
Describe the spreadsheet you need in plain language and it comes back structured, with sample data, ready to edit like anything else.
Nine built-in starters plus your account template library. A template carrying placeholders asks for their values, then hands you an independent copy.
A workbook already in your file store opens straight into the grid, with no download and re-upload in between. Link a form and the header row seeds itself, past responses backfill, and each new submission appends a row.
Say what you want the column to do.
Describe a formula in plain English and get one back with a line explaining it. Let a column finish itself from the pattern above. Ask a question about the tab and get an answer.
- Every action runs against a per-user rate limit, so nobody can run the bill up by holding down a button.
Generate Formula
Plain English in, a formula out, with a one-line explanation and a copy button.
Smart Fill
Reads the header and the values already in the column, then writes the next ones below your selection.
A Ceiling On Spend
Every action runs against a per-user rate limit, so nobody runs the account bill up.
Auto-Classify Columns
Detects each column type and applies the matching number format, using your account currency and never guessing one.
Data Query
Ask a question about the first tab. Get an answer, and often a formula to copy.
AI Actions on Selection
Rewrite, summarize or translate the active column and write the result back in place.
Summarise. Chart. Both in a side panel.
Pick the rows, the column, the value, and how to add it up, and the summary lands on a tab of its own. Neither the pivot nor the chart floats over your cells.
Pivot Tables
Pick row fields, an optional column field, a value field, and an aggregation of sum, count, average, min or max. A live preview renders the first rows before you commit.
SVG Charts
Column, bar, line, area, scatter, pie and donut, drawn in a side rail and recoloured to the workbook theme.
Filter & Preview
Apply an equals-filter on a field and the preview recomputes instantly.
Lands on a New Tab
The computed grid arrives on its own tab as plain values. Build it again when you want the newer picture.
Side-Panel by Design
Charts and pivots live in their own rails, never floating over your cells.
Numeric Guards
Pick a value column with no numbers and the panel says so rather than drawing something broken.
Pull the table onto a tab instead of exporting one.
A balance sheet, a profit and loss, the invoice register, your product table or your billing metrics, dropped onto a new tab.
Straight from Ledger and Catalog
The financial statements, the invoice register, and the product table the rest of the platform already sells from.
Amounts arrive unformatted
As raw numbers, so your own account currency formatting applies rather than one somebody else picked.
A snapshot, deliberately
The tab is the picture at the moment you pulled it, not a live link rewriting your work. Pull it again for a newer one.
Read a row back the other way and it becomes a real invoice.
A line-item table becomes a receivable invoice with a contact attached. A row becomes a task with an assignee and a due date.
An invoice in Ledger
Description, quantity and unit price per row. Pick a contact, create it, and open the invoice.
A task in Dispatch
An assignee, a due date, and a link back to the sheet, so whoever picks it up opens the numbers behind it.
Sent from one panel
Out to email, an internal message, a live screen or a channel post, with no export in between.
And it carries on
The records a row writes to are the ones the rules engine already watches.
A spreadsheet is usually where work goes to stop. Somebody models the quarter, agrees it in a meeting, and then retypes the result into the systems that actually run. A row that becomes an invoice closes that gap, because the model and the operation are the same database.
A spreadsheet is only as current as its last export.
Unless there was never an export.
The columns they may not see never reach their browser.
Name the columns or the whole tabs a member must not see, and those cells are stripped before the workbook leaves the server.
- The Cost column was stripped before the workbook left the server. There is no value here to reveal.
- Everything else stays editable, and a whole tab can be withheld the same way.
Stripped, not hidden
Hiding a column is a display setting anybody can undo. Purview takes these out of the response entirely.
The rest stays live
What they can see stays editable, and only the restricted cells render locked.
Comments inherit it
A thread carries the visibility of the cell it is pinned to, so a redacted tab cannot be discussed into the open.
Share a spreadsheet as a read-only public page.
A link anyone can open, with a copy button and a QR code in the dialog. Sharing by name is a separate thing entirely.
Read-only by design
What a reader gets is the title and the grid. No save, no toolbar, no share button, no way in.
Out of search results
Search engines are told to skip it, so a link you sent to one person does not turn up in results.
Revocable
Unpublish and the link stops working. Publish again and you get the same link back, not a second one to track.
On your site, or in the portal
The same workbook renders inside Sites and Navigator, and Purview redaction still applies to the published page.
Take it out, or take it back.
XLSX, CSV and PDF from one screen that also prints. Every save keeps a snapshot you can compare cell by cell and restore.
XLSX Export
The full workbook: every tab, its values, and its formula strings.
CSV Export
The first tab flattened, carrying computed values rather than the formulas behind them.
PDF Export
A paginated table with a title and page numbers, from the same screen that drives print.
Version History
Compare any two versions and see each cell that changed, old and new, side by side. Restoring one writes a fresh version rather than deleting the newer work.
Sharing
Invite people by email at view, comment, or edit. Change or revoke a permission in place without re-inviting anybody.
In Docs and Slides
A range sits inside a document as a linked table rather than a pasted copy, and a chart on a slide reads two ranges from here.
The same six questions, answered either way.
What a Sheets subscriber picks up next.
5 of these 5 connections are in your plan today. The rest stay visible so you know the instrument is there before you need it.
Docs
A range from a workbook sits inside a document as a linked table rather than a pasted copy.
Slides
A chart on a slide reads its labels and values from two ranges here, so redrawing it picks up whatever changed.
Forms
A linked form seeds the header row, backfills every past response, and appends a row per submission after that.
Depot
Workbooks are stored in the shared file store, opened from it without a download, and filed back into a folder from the editor.
Agenda
The same Calisto Work subscription, so a workbook and the calendar the meeting sits on are one plan.
No setup cost. Pay when you start using.
Spreadsheets for the whole team.
Calisto Work is one subscription for Docs, Sheets, Slides, Forms, Agenda, and Depot. Sheets is coming soon.

Questions about Calisto Sheets
You can pull live tables from Ledger and Catalog onto a tab. The model is built where the real numbers already live rather than on an export that was correct on the day it was taken.
Yes. A row can become an invoice or a task, which is the step that usually falls out of a spreadsheet and into somebody manual routine.
A formula engine, pivot tables and SVG charts, in the browser. It is a spreadsheet rather than a table view with arithmetic.
Yes, with formulas where they map. What changes afterwards is usually replacing the pasted export with a live table.
The pricing section on this page reads the live catalogue and is the authority. Sheets works without the rest of Calisto Work.
Yes, to standard spreadsheet formats, plus bulk export of the store.
