Turn a Two Hour Excel Slog Into a 10-Minute Task With Claude in Excel

In this guide, you’ll learn how to use Claude as a spreadsheet architect. You’ll take multiple messy CSVs and have Claude clean the data, format tables, color-code tabs, and turn the workbook into a useful dashboard. The source example used 7 unlabeled CSVs of SEO data and produced a dashboard in under 10 minutes.

• Consultants with clients who love spreadsheets
• Team leads who want to standardize reporting processes across their organization
• The “Excel person” on the team who spends the end of each month cleaning up formulas and tables

You’ll build a cleaned, formatted Excel workbook that combines several raw CSVs into a master dashboard and can be reused as a monthly reporting template.

• Renamed and reformatted worksheet tabs
• Cleaned tables for each data source
• A master report sheet that ties the data together
• Charts for dashboard components
• A README tab explaining how to use the template

• Microsoft Excel
• Any paid Claude plan
• 3–10 CSVs of raw data
• Optional: sales data, expense tracking data, SEO data, or another dataset you report on each month

• Use Claude for Chrome to log in to your CRM and export the source data for you.
• Set this up as a recurring workflow to run at the end of each month so you can see trends over time.
