How to convert CSV to IIF

  1. Drop your CSV file into the converter above.
  2. Confirm the detected Date, Description and Amount columns.
  3. Choose IIF and download — then import it into your software.

Why convert to IIF?

  • IIF lets QuickBooks Desktop users push transactions straight into a bank register.
  • No sign-up to try. Pay per conversion with credits that never expire within 12 months — no subscription required.

About the formats

Comma-separated values: A plain-text table, one transaction per row. Every bank exports it, but column names and sign conventions differ from bank to bank, which is why imports often fail.

Intuit Interchange Format: A tab-delimited format QuickBooks Desktop uses to import transactions directly into a register, with full control over accounts.

Questions

Is it safe to convert my CSV file here?

Bank exports and text-based PDFs are processed directly in your browser and never uploaded. Scanned statements are only uploaded if you choose OCR; they are processed by Microsoft Azure and Anthropic and not stored afterwards.

How do I know the conversion is correct?

When the source contains opening and closing balances we reconcile them against the sum of every transaction and flag any difference before you download.

Will QuickBooks accept the file?

Yes — IIF files import via File › Utilities › Import › IIF Files in QuickBooks Desktop. Make sure the account name you enter matches your QuickBooks bank account exactly.
