Why Parse 835 Remittance Advice to Excel?

The X12 835 transaction set (Remittance Advice / ERA) tells providers how a payer adjudicated each claim — what was billed, what was allowed, what was paid, and why the rest was adjusted or denied. Converting an 835 to Excel lets billing teams reconcile payments against claims in a familiar spreadsheet, spot adjustment patterns via CAS reason codes, and feed clean payment data into accounting systems — all without sending the file to a remote server. This tool performs structural parsing only; it does not validate or certify data against any medical, financial, or legal schema.
