Mog Spreadsheet

Open .xlsx workbooks directly in VS Code and Cursor with Mog's spreadsheet runtime.

Mog brings a full spreadsheet experience into the editor: workbook loading, grid editing, formula recalculation, formatting, sheet navigation, and XLSX save/export through the same engine used by Mog's browser spreadsheet app.

Features

• Opens .xlsx files as a VS Code custom editor.
• Lets you inspect and edit workbook data without leaving your code workspace.
• Saves workbook changes back to XLSX.
• Uses Mog's Rust-backed compute engine and web spreadsheet UI.

Usage

Open an .xlsx file and choose Mog Spreadsheet when VS Code asks which editor to use. To make it the default, use Reopen Editor With... and select Mog Spreadsheet.
