The FinancialDataTools.com IIF to Excel Converter is a free, browser-based tool for converting QuickBooks IIF files directly to Excel XLSX format. It runs entirely in your browser — no file is ever uploaded to any server.
How It Works
Drop your IIF file onto the left panel or click Open to browse. Your source data is previewed in a table. Click Convert to Excel to build the workbook in the right panel. Click Export XLSX to download the result file.
Privacy and Security
All file processing happens inside your browser using JavaScript. No file content is transmitted to any server. Your financial data stays private on your device.
Is the IIF to Excel Converter free?
Yes, completely free with no signup required.
Does my file get uploaded to a server?
No. All processing is local in your browser. Nothing is uploaded.
How is this different from the IIF to CSV version?
This tool outputs a native Excel XLSX workbook rather than a plain CSV text file, so you can open it directly in Microsoft Excel or Google Sheets without an extra import step.
