Excel
Truncation.
Does your bank account number look like 1.23E+15? Excel destroys long numbers. Wrap them in the Safe-Text Mask.
Source CSV Stream
Hardened Output
Protocol Insight
We wrap numeric strings longer than 12 digits in the ="NUMBER" format. This forces Excel to treat the cell as Text, bypassing the IEEE 754 truncation bottleneck.
IEEE 754 Limit
Excel stores only 15 significant digits. Any digit beyond this is permanently zeroed out by the engine.
Permanent Loss
Once you save a truncated CSV in Excel, the original data is destroyed forever. There is no 'Undo'.
Pro Workflow
Always use the 'Data → From Text/CSV' wizard to manually set column formats to 'Text' for 100% safety.
Tired of Truncation?
Our bank-specific engines handle transaction IDs as pure text strings, ensuring 100% forensic precision without the scientific notation headache.
