Automate Email Expense Tracking with Claude for Chrome

In this guide, you’ll learn how to track and label expenses from Gmail into Google Sheets in a couple of minutes using Claude for Chrome. You’ll produce a populated expense-tracking sheet and use Claude as a personal assistant without building complex automation chains.

• Small business owners
• Freelance consultants
• Anyone with monthly expense reports

You’ll build a reusable Claude for Chrome workflow that finds software subscription receipts in Gmail, labels relevant emails, archives non-receipts, and fills a Google Sheet with expense details.

• A Google Sheet with expense headers such as Expense Title, Company, Amount, Date, and Renewal Date
• Rows populated from software subscription receipts
• A total row at the bottom of the sheet
• A repeatable prompt you can reuse for future months

• Claude account, pro or above
• Claude for Chrome extension
• Google Chrome desktop app
• Google Sheets
• Access to the Gmail inbox you want Claude to search
• A month and year to search for software subscription receipts

• Save your prompt as a shortcut by typing / and selecting “Create shortcut.” You can keep using the same Google Sheet and tell Claude which month to run each time you use it.
• Once you have a shortcut set up, you can have it run daily or weekly on a schedule.
