What changes

Plain text rows are normalised by our table engine before CSV is written, preserving row order and typed values for txt-to-csv.
Flat TXT columns stay flat in CSV; presentation-only details are not carried forward.
The converter treats the file as one logical table, so comments, prose around tables, and source metadata are skipped.
Numbers, booleans, dates, blanks, and strings are inferred and then serialized in the destination format's native shape.
Delimiter, encoding, newline, and header choices apply only where TXT or CSV is a text table.
The CSV result focuses on portable data, not formulas, rich layout, or application-specific metadata.

A real Plain text → CSV run

We converted our Plain text sample (440 B) with Table engine on 2026-09-11. It took 1 ms and produced a 446 B CSV file, about the same size as the input. The engine raised no warnings.

Input · sample.txt · 440 B

header: Treat the first delimited row as field names instead of generated column labels.
quote: Set the quote character used when parsing CSV, TSV, or TXT fields.
encoding: Decode UTF-8 or Latin-1 text before parsing table-oriented formats.
newline: Write LF or CRLF line endings for generated text tables.

Plain text to CSV by API or MCP

The HTTP API and the MCP server run the exact engine this page uses (Table engine); the response carries the same warnings the web converter shows. Check support first with GET /api/v1/pairs?from=txt&to=csv.

curl

curl -X POST https://filetypeconverters.com/api/v1/convert \
  -H "Authorization: Bearer $FTC_API_KEY" \
  -F "file=@input.txt" -F "from=txt" -F "to=csv" \
  -F 'options={"delimiter":","}' \
  --output output.csv
