About this flow
Remove wholly empty records, select identifier/category fields, expand exact categories into indicator columns, and download a TSV matrix. Review complete original/intermediate/final downloads and the exact documented transformation.
Limitations
- One UTF-8 file, at most 1 MiB, 1,000 data rows, 20 input columns and 20,000 input cells. Downstream expanded files must fit each original processor limit. Original and intermediate downloads retain removed data; this is not redaction. Select columns before encoding. Exact first-seen category strings include empty values, case and whitespace distinctions. Other selected cells remain text; no training, scaling, statistical validity or type inference. Expansion must stay below 500 output columns/500,000 cells. Formula protection off for literal matrix/identifier bytes; import as text.
- Chromium viewport proof does not certify native Excel, other browsers, physical devices, heap/forensic erasure or destination semantics.
- Choose a saved comma-delimited CSV input; the first step fixes comma parsing. TSV input is not offered by this recipe.
