What's inside the CSV bundle?

1. The bundle contains one CSV per section of your return that has data (empty sections are simply omitted):

2. b2b.csv - every B2B invoice, one row per item line (Table 4). b2cl.csv - large inter-state consumer invoices (Table 5).

3. b2cs.csv - consumer sales aggregated by state and rate (Table 7), with Place-of-Supply written as code + name, e.g. 27-Maharashtra.

4. cdnr.csv - registered credit/debit notes (Table 9B), signed: credit notes negative, debit notes positive.

5. supeco.csv - Table 14, one row per marketplace operator. hsn_b2c.csv and hsn_b2b.csv - the Table 12 HSN summaries. doc_issued.csv - Table 13 invoice-series ranges.

6. The rows are byte-for-byte identical to the expandable sections in the detailed view and to what the JSON carries - one source of truth, three views of it.
