See what users say about converting CSV files into OFX format
I received transaction data in CSV but needed OFX for our finance software. The converter kept the dates, amounts, and descriptions aligned, so the file was ready to import.
Our expense records came from several CSV exports, and this gave me one consistent OFX file for reconciliation. It reduced the formatting checks I normally do before an import.
I converted a large CSV of historical transactions into OFX for an account migration. The output processed cleanly and saved me from mapping every entry by hand.

Frequently Asked Questions
What’s the best CSV to OFX converter online in 2026?
FinanceFileConverter is the best tool to convert bank CSV exports into clean, accurate OFX files in seconds.
Can I convert or merge multiple CSV files at once?
Yes. Upload multiple CSV files in one batch, keep the OFX outputs separate, or merge consecutive CSV exports for the same account into one OFX file. Do not merge files from different accounts or clients because one OFX statement carries one account identity.
Will my financial data stay private?
Yes. CSV files are processed in the browser during conversion and removed from the conversion session after the OFX file is generated. This keeps your financial data private and safe.
Do I need to install anything?
No. The CSV to OFX converter runs online in your browser, so you can work with files and create OFX output without installing a desktop app.
How to open an OFX file?
OFX stands for Open Financial Exchange. To open an OFX file, import it into compatible accounting or money-management software. Because it is a structured text format, you can also view it in a text editor, but that will show raw tags rather than a transaction table. Here, “open” can mean viewing the raw text or importing the data into software.
How do I import an OFX file into QuickBooks Desktop?
QuickBooks Desktop generally expects a QuickBooks Web Connect .QBO file rather than a plain .OFX file. Use the CSV to QBO converter for bank or credit card payments, then import the QBO file through Bank Feeds.
What information is required to create the OFX file?
Choose the account type, enter the account number, and confirm the currency. Bank or routing ID and closing balance are optional. You will also review the CSV date, description, amount, debit or credit, and reference columns.
Does the converter support credit card CSV files?
Yes. Select Credit Card as the account type and confirm whether charges in the CSV are shown as positive or negative. The converter creates the matching OFX credit card statement structure.
Can I adjust the detected CSV mapping?
Yes. Before conversion you can change the date format, date and description columns, amount layout, debit and credit columns, reference column, and sign direction.
