Tab Groups for Excel

A side panel for Excel that organises the sheets in big workbooks: group tabs the way a browser groups tabs, jump between sheets, hide or show whole groups at once, and colour tabs by group. Group assignments are saved inside the workbook, so a file grouped by one person shows the same groups to everyone who has the panel.

Install — once, about a minute, no admin rights needed

1. Unzip both files into a folder you'll keep, e.g. Documents\Tab Groups. Excel reads from this folder, so don't delete it afterwards.
2. Right-click sideload Claude.ps1 → "Run with PowerShell". If nothing seems to happen, open PowerShell in that folder and run: powershell -ExecutionPolicy Bypass -File ".\sideload Claude.ps1"
3. Close Excel completely and reopen it.
4. Click Tab Groups at the right-hand end of the Home ribbon. (Not there? Home → Add-ins → More Add-ins → Developer Add-ins.)

Using it

• Drag any sheet row onto a group to move it there; drag onto "Ungrouped" to take it out. Tab names are never changed.
• To create a group: tick sheets (checkbox appears on hover), type a name in the bottom box, click "Group N sheets".
• Hover a group header for Rename and Hide/Show.
• The panel updates itself automatically — install once, that's it.
