How to get your CSV

Most banks and cards

Sign in on a computer, open the account, look for Download, Export, or Statements, choose CSV, and pick the last 12 months.

QuickBooks or Xero

Run a transaction report for the last 12 months (for example, “Transaction List by Date” in QuickBooks) and export it as CSV.

Cash App

In Cash App on the web, open Activity, then Statements, and export your transactions as CSV.

The file needs a date, a description or merchant name, and an amount. Most exports have these already.

What we check

  1. Duplicate charges. The same vendor billing the same amount twice within days.
  2. Silent price increases. Recurring bills that crept up without notice.
  3. Fees you can avoid. Overdraft, late, service, and interest charges.
  4. Look-alike payees. New payees with names almost identical to vendors you trust, a common invoice-fraud trick.
  5. Every subscription. A full list of recurring charges, so you can cut what you don’t use.
