  • Tally.imp log file records exact line numbers and failure reasons.
  • TrulyInvoice syncs F9 Purchase Vouchers directly via Port 9000 without raw XML files.

Common Tally XML Import Errors & Immediate Fixes

SyntaxError / Special Characters

Unescaped '&', '<', or '>' in narrations causes parsing to crash. Solution: Replace '&' with '&amp;' in source data before XML generation.

Date Out of Range / Invalid Date

Voucher dates outside company financial year or wrongly formatted. Solution: Convert all dates to YYYYMMDD format in XML.

Voucher Master Mismatch

Party ledger or stock item name in XML does not match Tally master spelling. Solution: Pre-create masters or clean trailing spaces.

Memory Access Violation / Corrupted File

Power cut during XML import or corrupted company data index. Solution: Press Alt+Y > Repair after taking full data backup.

Standard Tally XML Structure for Purchase Vouchers

Frequently Asked Questions

What causes Tally XML import error 'Semicolon Expected' or 'SyntaxError'?▾
This is caused by unescaped special characters (e.g. '&', '<', '>') in Narration or Party Name fields. In Tally XML, '&' must be written as '&amp;'. Removing special characters or escaping them resolves the error.
How do I read the Tally.imp error log file?▾
When an XML import fails in Tally Prime, check the `Tally.imp` file in your Tally installation folder (e.g. C:\Program Files\TallyPrime\Tally.imp). It details the exact line number, voucher date, and reason (e.g. 'Stock Item not found' or 'Date out of range').
How to fix Tally company data corruption 'File Damaged' error?▾
Take a complete backup of the data folder first. In Tally Prime, press Alt+Y (Data) > Repair (or Help > Troubleshooting > Repair). Select the company and confirm 'Backup before Repair: Yes'. Tally rebuilds corrupted indices.
