Build a monthly client report in Google Sheets with Claude

Description and use

Using Claude in Google Sheets speeds up monthly client report creation by automatically matching data, building summary tabs, flagging over‑budget retainers, and generating charts, with all edits presented as approval cards.

Problem

A single person in a small business manually rebuilds monthly client reports in Google Sheets, fixing formulas and writing summaries for partners.

Outcome

The process becomes reproducible, faster, and less error‑prone. The manager can run the same request each month, with all edits tracked in version history and approvals ensuring control.

Workflow

• Open the monthly report sheet in Google Sheets
• Launch Claude via Extensions → Claude → Open Claude
• Set "Ask before edits" mode
• Ask Claude to match hours to invoices by client, add a summary tab, flag retainers over 10% budget, and chart top ten clients
• Review each suggestion card and accept or dismiss changes
• Ask Claude for a five‑line summary and insert it into the partners’ Google Doc
• Save the sheet and document for future reuse
