Start from the raw export
Keep the original Tally export as evidence and do cleanup in a separate workbook. This makes it easier to answer questions later when a client, owner or accountant asks where a value came from. A clean copy should preserve voucher numbers, ledger names, dates, amounts and references without changing the meaning of the original rows.
- Save the raw export first
- Work in a separate cleaned file
- Preserve voucher and ledger identity
