Features

• Open CSV, TSV and delimited TXT; drag and drop supported
• Detect comma, semicolon, tab or pipe and supported encodings
• Diagnose quoting, uneven rows, blank records and header problems
• Warn about formula prefixes, leading zeros and long numeric identifiers
• Review explicit repairs in source and before/after previews
• Export UTF-8/BOM, selected delimiter and CRLF/LF with a JSON report

Limitations and safety

16 MiB input, 100,000 records, 256 columns and 1,000,000 cells. This is a single-file in-memory tool, not a spreadsheet or batch converter. Original files and existing output/report files are not overwritten. Content-changing repairs are opt-in; rows/columns are never silently removed and identifiers are not converted to numbers/dates. Failed strict parsing blocks export; alternative quote/encoding interpretations require explicit review. CSV cannot prevent Excel from later reinterpreting data: import identifier columns as Text. Optional formula-risk apostrophe prefixing changes cell text and is not a universal security defense. Preview is bounded; export uses the parsed data. A report-write failure after a saved copy is reported as partial export.

Expected SHA-256: bba87c59320c96d0015afdf20435a09229baf9f03a9be5319f7b7152eb45bf29

Compare with the accompanying SHA256SUMS.txt. A matching hash confirms the published bytes; it is not a malware scan or an Authenticode signature.
