LaTeX table to reStructuredText grid table 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 input extracts rows containing ampersand-separated table cells. It does not compile TeX or render an entire LaTeX document.

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

Output options

Generate a reStructuredText-style grid table for Sphinx or Docutils source. The table is plain text with width-sensitive borders.

Conversion rules

How the input is read

• Provide the tabular rows needed for conversion, with ampersands between cells and row terminators.
• The importer splits table text; it does not evaluate macros, packages, math or custom column definitions.
• Simplify multicolumn/multirow constructs and literal ampersands before extraction.
• Formatting commands can remain text in extracted cells; clean them when the destination expects plain values.

How the output is written

• A header separator distinguishes the first row from body rows.
• Use a monospaced source editor and inspect multiline or wide Unicode cells.
• Test the grid with the actual Docutils/Sphinx renderer before publishing.

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.
