Splitwise keeps your full expense history, and you can get a copy of any group as a CSV spreadsheet. The button moves around between app versions, so here is where it lives in each place as of 2026.

On the website (easiest)

  1. Log in at secure.splitwise.com.
  2. Open the group you want to export from the left sidebar.
  3. Click the group's settings (gear icon or "Group settings" link).
  4. Scroll to "Export as spreadsheet" and click it.
  5. Your browser downloads a .csv file named after the group.

In the mobile app

  1. Open the group, tap the gear / settings icon.
  2. Scroll down to Export as spreadsheet.
  3. The app emails the CSV to your account address or offers a share sheet, depending on version.

What's in the file

One row per expense with columns for Date, Description, Category, Cost, Currency, then one column per group member showing each person's net balance change for that row. Settle-up payments appear as rows with the category Payment. The last line is a running "Total balance" summary. Repeat the export per group — Splitwise exports one group at a time.

What you can do with it

  • Keep it as a backup. Your history in a format any spreadsheet opens.
  • Analyze it. Pivot tables on a year of shared groceries are more interesting than you'd expect.
  • Recreate the group elsewhere. Splitpond reads this exact format: drop the CSV on the homepage and you get a link-based group with the full history and identical balances — no accounts for anyone, no expense limits ever.

Tip: export before deleting your Splitwise account — deletion removes your access to the data, and support can't retrieve it for you afterwards.
