CSV2IIF is a specialized financial data converter developed by ProperSoft that transforms bank and credit card transactions from standard spreadsheet formats into Intuit Interchange Format (IIF) files. This tool bypasses manual data entry, enabling swift data imports directly into QuickBooks Desktop. Key Capabilities
Format Transformation: Seamlessly converts .csv, .xls, .xlsx, and .txt files into QuickBooks-compliant .iif files.
Legacy Software Lifesaver: Allows businesses using QuickBooks versions older than three years to import bank data even after their official Web Connect (QBO) features expire.
Dual-Account Logic Parsing: Intelligently maps transactions to ensure they satisfy the IIF required dual-account framework (e.g., matching a bank account entry to an expense or income category).
Sign-Reversal Control: Features a one-click toggle to reverse transaction signs (+/-), instantly fixing credit card statements where expenses appear as positive values. Detailed Processing Features
The application incorporates several automated and customizable settings to guarantee data alignment: Functionality Interactive Column Mapping
Matches your spreadsheet headers (Date, Amount, Payee, Check Number, Memo) to specific QuickBooks destination fields. Sub-Account Notation

Manages complex line items containing multiple expense allocations through dedicated split-category mapping. Step-by-Step Conversion and Import Workflow
To ensure seamless data migration into your software, follow this sequence:
Format Your Spreadsheet: Prepare your file with one transaction per line. Ensure it includes core details like date, amount, payee, and the correct QuickBooks account/category names.
Run the Software: Download and start the ProperSoft Convert App. Load your source spreadsheet file into the converter interface.
Map and Convert: Match your headers to the IIF template, verify accuracy in the preview screen, and click Convert to generate the .iif file.
Back Up QuickBooks: Always back up your accounting records (File > Back Up Company) before running an automated import.
Execute the Import: In QuickBooks Desktop, navigate to File > Utilities > Import > IIF Files and open your newly created document. If you are trying to resolve an import problem, tell me: What version and year of QuickBooks are you using?
Are you getting a specific error code or failing validation?
Is your source data from a bank statement, credit card, or custom software?
I can provide the precise formatting or troubleshooting steps for your exact setup.
