Why Use Our Column Mapper

Every bank and financial institution exports CSV files with different column names and formats. Some call it "Transaction Date" while others use "Date Posted" or "Posting Date." Our Column Mapper normalizes all these variations into a consistent, standard format. Whether you're consolidating data from multiple accounts, preparing reports, or importing into accounting software, you no longer need to manually rearrange columns or write complex spreadsheet formulas.

FAQs

What standard fields are supported?

Our mapper supports eight standard fields: Date, Amount, Description/Payee, Type (credit/debit), Category, Reference/Check#, Memo/Notes, and Balance. These cover the vast majority of financial CSV formats from banks and accounting software.

Can I map multiple columns to the same field?

No, each standard field can only be mapped from one source column. If multiple source columns map to the same field, only the last mapping will be used. We flag duplicate mappings and unmapped columns to help you avoid data loss.

Is my data secure?

Absolutely. All processing is done locally in your browser using JavaScript. Your CSV financial data is never uploaded to any server, ensuring complete privacy and security of your sensitive information.
