## Questions and answers from the visible page

### What format should I paste my data in?

One invoice per line, comma-separated: InvoiceNo,TaxableValue,GSTAmount — for example: INV001,10000,1800. You can export this format from most accounting software or build it in a spreadsheet.

### How does the tool match invoices?

By invoice number (case-insensitive), then compares taxable value and GST amount with a ₹1 rounding tolerance — anything outside that tolerance is flagged as a mismatch.

### Is my invoice data uploaded anywhere?

No — this tool runs entirely in your browser. Nothing is sent to any server; the comparison happens locally on your device.
