What this page does
The table snapshot prepares CSV/XLSX for export: sheets, headers, columns and row reading rules. It is used when the source is tabular.

How to use it
- Open table snapshot after receiving the file.
- Choose sheets to read.
- Select header row or automatic detection.
- Merge sheets into one row stream if needed.
- Configure fields and check preview.
Expected result
- Eofferix knows which rows and columns to use.
- Rows before headers can be skipped.
- Several sheets can be read as one source.
Common issues
- Wrong header row creates wrong field names.
- Merged sheets should have compatible columns.
- Empty rows and service sheets should be excluded.
