The file tool library
Finance & Data Files
Finance and data file tools convert and check bank exports, payment files and spreadsheets. The OFX and QFX to CSV converter turns a bank statement into spreadsheet rows, and CSV to QIF goes the other way for finance apps that accept Bank-profile QIF files. The CSV difference checker finds changed records between two exports, and the CSV encoding converter fixes unreadable accents by converting to UTF-8.
For payments, the NACHA ACH file preflight checks a supported PPD or CCD file's structure before you review it with your bank, and the ABA payment file generator builds an Australian direct-credit file from a CSV. The UBL invoice preflight checks common fields and totals in an e-invoice XML file.
Files are processed in your browser and are not uploaded. These are preflight checks on a supported subset, not bank or tax-authority certification, so always use your bank's or authority's own validation before submitting.
