Understanding Column Mapping

Every bank formats its CSV exports differently. Chase might put the date in column A and the description in column B, while Bank of America uses completely different column names and ordering. Column mapping is the process of telling our converter which CSV column contains each piece of transaction data.

Our CSV to OFX converter automatically detects common column names like “Date”, “Description”, “Amount”, “Credit”, and “Debit”. If your bank uses non-standard headers, you can manually select the correct column for each field using the dropdown menus. The tool also supports banks that use separate credit and debit columns instead of a single amount column.

Optional fields like Memo and Check Number can also be mapped if your bank provides them. These fields are included in the OFX output as MEMO and CHECKNUM tags, which some accounting software uses for additional categorization.

OFX Compatibility with Financial Software

The OFX format is supported by an extensive range of financial software. Our converter generates OFX v1.02 (SGML-based) files, which have the broadest compatibility across both modern and legacy applications. Here's how to import OFX files into popular software:

Supported Date and Amount Formats

Our converter handles multiple date formats commonly used by US and international banks: MM/DD/YYYY, MM-DD-YYYY, YYYY-MM-DD, YYYY/MM/DD, and 2-digit years (MM/DD/YY). For amounts, the tool automatically strips currency symbols ($, EUR, GBP, JPY), commas, and spaces. Parenthesized negative values like (123.45) are correctly interpreted as -123.45.

Banks that separate credits and debits into different columns are fully supported. Simply toggle the split-column option and map each column independently. The converter calculates the correct signed amount for each transaction automatically.
