It performs the supported work locally, so the source does not need to be sent to a conversion service. Use the ACH setup extractor with an approved source and a clearly defined expected result.
Start with a trusted ACH file containing the file header and batch settings you want to inspect. Work from a copy, preserve leading zeros and remove unrelated report headings or totals that could be mistaken for transaction data.
Use the on-page controls, then compare the displayed batch count, entry count, total debits and total credits with the source expectation. Investigate warnings instead of assuming that a downloadable result is correct.
The expected result is a readable summary of destination, origin, company, ODFI, SEC and other reusable configuration values. Before transmission or downstream import, review whether values are current, whether multiple batches use different settings and which fields your bank controls, save the source separately and follow your organization’s approval process.
Confirm that the selected input really contains a trusted ACH file containing the file header and batch settings you want to inspect. A renamed extension does not convert a spreadsheet, PDF or binary export into a valid ACH-related source.
Compare entries one batch at a time. Missing rows, duplicated rows, amount scaling, debit-versus-credit selection and malformed addenda can all change counts or monetary totals.

Always confirm bank-specific settings with your financial institution before uploading a production file.
