How do I configure the Books file columns (header row, party, date, TDS amount)?

Last updated on Sep 08, 2026

Short Answer: Open 'Configure file - Books', set 'Header row', choose 'Party / Customer Name' for party, 'Voucher Date' for Date, and 'TDS Receivable (Rs.)' for TDS amount; verify via Live normalized preview.

PreRequisites

  1. Books file uploaded and 'Configure file - Books' modal open.

  2. You are on the 26AS TDS reconciliation flow.

Steps

  1. Open the 'Configure file - Books' modal. It appears after Continue or when configuring the Books file.
    Data preview shows rows from your Books file Data preview (20 rows).

  2. Set 'Header row' to the row number that contains column headers using the dropdown.
    Column headings align correctly in the Data preview.

  3. Set 'Party / Ledger name' to 'Party / Customer Name'.
    Party names display correctly in the preview.

  4. Set 'Date' to 'Voucher Date'.
    Dates appear normalized in the Live normalized preview.

  5. Set 'TDS amount' to 'TDS Receivable (Rs.)'.
    TDS values populate in the preview.

  6. If a required column is missing, click 'Add column' and create/derive the column required for mapping.
    New column appears and can be selected in mapping dropdowns.

Troubleshooting

  1. Dates display as '2025-04-10T00:00:00' or incorrect format.
    LikelyCause: Wrong header row selected or wrong column mapped as Date.
    Action: Change 'Header row' to the correct row and re-select 'Voucher Date' as the Date column; confirm with Live normalized preview.

  2. TDS column not available in mapping dropdown.
    LikelyCause: Header row misaligned or the column header is different.
    Action: Adjust 'Header row' so headers are recognized or use 'Add column' to create/rename the TDS column before mapping.

Note: Use the 'Live normalized preview' to confirm mappings before you proceed. Header row in example is set to '4'.
