About this flow
Prepare a table for a tab-separated import: remove entirely empty rows, keep the first exact duplicate, and export TSV. Choose the actual source delimiter and inspect the intermediate CSV or TSV before downloading the final TSV.
Limitations
- The first row remains the header. Whitespace-only rows are retained; exact duplicate comparisons preserve case and whitespace.
- The final TSV quotes every cell and uses CRLF line endings. Quoted tabs and newlines remain part of their original cells.
- Final formula protection preserves complete bounded signed decimal/exponent numbers and adds an apostrophe to formula or control-prefixed expressions. CSV/TSV imports may infer types; import identifier columns as text. Protection OFF retains literal expressions with spreadsheet execution risk.
- Original and downstream inputs must fit the 5 MiB processing limit; a final TSV may grow up to 20 MiB.
- Use UTF-8 text with a consistent number of fields per row. Ragged rows and malformed quoting fail before processing; blank physical lines in a multi-column table must be represented as correctly shaped empty records.
- A table may contain up to 50,000 data rows, 500 columns and 500,000 cells. Processed files quote every cell and use CRLF record separators.
