Bank Statement Formats Explained: PDF, CSV, OFX, QFX, and More
Your bank offers multiple download formats, but which one should you use? This guide explains each format's strengths, limitations, and the best use cases for accountants and bookkeepers.
Try for one weekThe Format Confusion Problem
Every bank statement download page presents multiple format options. Most accountants default to PDF because it's familiar, but this creates hours of manual data entry work that could be avoided.
Common Scenario
A client sends their bank statement as a PDF. You need to import the transactions into QuickBooks. Your options:
- Option A:Manually type each transaction (1-2 hours for 100 transactions)
- Option B:Ask client for CSV/OFX download (delays, often unavailable for past months)
- Option C:Convert PDF to QBO format automatically (2 minutes)
Understanding each format helps you choose the right approach for every situation.
