What changes

HTML rows are normalised by our table engine before CSV is written, preserving row order and typed values for html-to-csv.
Flat HTML 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 HTML or CSV is a text table.
The CSV result focuses on portable data, not formulas, rich layout, or application-specific metadata.

A real HTML → CSV run

We converted our HTML sample (490 B) with Table engine on 2026-09-11. It took 1 ms and produced a 42 B CSV file, 91% smaller than the input. The engine raised no warnings.

Input · sample.html · 490 B

Standalone document with 1 heading, 1 paragraph, 1 table, 0 links, 0 images

Headings: 1
Paragraphs: 1
Tables: 1

Standalone document: yes

Output · sample.csv · 42 B

2 data rows × 3 columns; header: Metric,Q2,Q3

Options

newline: Write LF or CRLF line endings for generated text tables.

Example

input

<table><tr><th>name</th><th>score</th></tr><tr><td>Ada</td><td>9</td></tr></table>

df = pd.read_html("input.html")[0]
df.to_csv("output.csv", index=False)

HTML 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=html&to=csv.

curl

curl -X POST https://filetypeconverters.com/api/v1/convert \
  -H "Authorization: Bearer $FTC_API_KEY" \
  -F "file=@input.html" -F "from=html" -F "to=csv" \
  -F 'options={"encoding":"utf-8"}' \
  --output output.csv
