Free local tools / Repeat a comparison

Set it up once. See what changed next time.

Save the columns and rules you confirmed. Import your paid reconciliation configuration, or save a local comparison. Bring the next pair of exports back here, or use the compatible local CLI. No account, upload, or recurring charge.

1. Choose your exports

Two CSV exports with the same header schema, up to 5,000 rows and 2 MB each. Original files are never overwritten. Close the tab to discard working data; downloads you save remain on your device.

The expected or first export The observed or second export

2. Confirm a comparison, or restore yours

If you bought a hosted reconciliation, download its configuration from your order page. After losing browser storage, restore that order with your private recovery key. To compare against the paid files, first reselect them here and save a private local receipt, then run your next pair with that receipt.

Import a paid configuration download or a saved .recipe.json file Optional: previous run’s private receipt for a change-only report

Import the same saved recipe used for that receipt. A different recipe or rule version cannot be compared silently. Use history you saved yourself; review it before comparing if someone else supplied it.
