CSV to QBO Converter

qbofile.com converts bank CSV exports into QBO (Web Connect) files that QuickBooks Desktop actually accepts — and converts QBO/OFX/QFX files back into clean spreadsheets. Built for bookkeepers and small business owners whose bank feed broke mid-month and who just need this month's transactions into QuickBooks. What makes it different: - Everything runs in your browser. Files never leave your computer — enforced by the site's Content Security Policy, not just promised. - Auto-detects your bank's column layout, then shows you the first parsed transaction so you can verify it before downloading. - Stable transaction IDs mean re-importing overlapping date ranges won't create duplicates in QuickBooks — which matters, because credit card statement cycles never line up with calendar months. - Warns you before you hit QuickBooks Online's file size and transaction limits, and tells you where to split the file. - Works with any bank's CSV format. Three output layouts for the reverse direction. Converting single files is free and will stay free. No signup, no account, no upload.
