HTML table to PDF API

Code examples

These examples send the sample as multipart/form-data and save the returned bytes unchanged. Set TABLECONVERT_API_KEY in your environment.

Request parameters

This importer extracts table, row and cell contents from HTML markup. It is a table-data converter, not a whole-page browser renderer.

Send one source: data, file, or url. The examples below use the source mode appropriate for this format.

Output options

Render normalized records into a PDF table document using the API’s light or dark style and optional title. This is a data-table export, not a whole-page HTML renderer or TeX compiler.

Conversion rules

How the input is read

• Supply an HTML table containing explicit tr and th/td elements.
• Tags inside cells are stripped; CSS, links, images and page layout are not preserved as visual elements.
• Simplify colspan, rowspan and nested tables before conversion; the parser extracts cells rather than reconstructing browser layout.
• Multiple table elements are separate extracted tables; confirm which table your request converts.

How the output is written

• Save the binary response as a PDF; the table is paginated by the conversion renderer.
• The public PDF API uses title and theme; only theme=dark enables dark styling, while other values use the light table style. headerColor, showHead and description are ignored by this API renderer.
• Check page width, long values and supported character rendering in the result.

When to use this API

Responses and errors

Check the response before retrying. A new HTTP request is a new conversion and may use credits again.

Limits, billing and versions

Local previews accept up to 200 KB. The current API implementation allows one uploaded file up to 50 MiB, limits each multipart text field to 1 MiB, and gives v2 conversion tasks a 30-second deadline. Deployment limits may be stricter. Read the returned error before retrying; some parser or renderer failures return HTTP 500.

Live calls follow the API credit policy. Failed conversions are refunded; a completed conversion is not undone if the download connection later fails.

References and format specifications

Format references explain the underlying syntax. The conversion rules and samples above describe TableConvert’s implementation.
