Free CSV Column Auto-Mapper and Header Normalizer
Auto-detect common transaction columns from exported CSVs and generate a normalized CSV with standard headers for cleanup and imports.
Tool workspace
Run the tool below, then copy or reuse the cleaned output in your spreadsheet or finance workflow.
- • Paste any transaction CSV with its original headers intact.
- • The mapper detects common date, description, reference, amount, debit, credit, and balance columns.
- • Blank standardized fields stay blank so you can review what the mapper could not infer.
