Spreadsheet editor

By Simtheory Productivity

Create, edit, and manage spreadsheets with formulas, cell operations, and CSV/Excel export.

Available tools

Create spreadsheet

Creates a new spreadsheet from provided data (CSV string, JSON array-of-arrays, or blank with column spec) and renders it.

Edit spreadsheet

Apply edit operations to a spreadsheet: set cells, insert/delete rows/columns, replace all data, update column config, or manage sheets (add/remove/rename tabs).

Export spreadsheet

Export spreadsheet data as CSV string.

Find spreadsheet

Search for a spreadsheet by id, title, or content. Returns IDs and metadata.

Get spreadsheet context

Returns the full data and column config of a spreadsheet as CSV text for AI reasoning. Use before making edits. For multi-sheet spreadsheets, returns sheet names and can target a specific sheet.

Import spreadsheet from file

Import a CSV or Excel (.xlsx, .xls) file into a native editable spreadsheet, retaining all styles, formatting, merged cells, and column widths. The file must already be uploaded as a FileAsset.

Open spreadsheet

Loads and displays a spreadsheet in the chat UI.
