Things to check before integrating
Before you integrate
Remove presentation macros and simplify merged columns before exporting plain cell values.
Before you integrate
Generated columns contain text; review escaping and cast dtypes explicitly instead of assuming a typed DataFrame.
Code examples
These examples send the sample as multipart/form-data and save the returned bytes unchanged. Set TABLECONVERT_API_KEY in your environment.

Authentication
Send Authorization: Bearer YOUR_API_KEY. Let the HTTP client set the multipart boundary; do not set Content-Type manually.
Keep production API keys in server-side environment variables.
Request parameters
This input extracts rows containing ampersand-separated table cells. It does not compile TeX or render an entire LaTeX document.
| Parameter | Type | Default | Description |
|---|---|---|---|
data | string | — | Inline LaTeX table content. Choose one of data, file or url. |
file | binary | — | Upload a tex file using multipart/form-data. |
url | string | — | A supported publicly accessible HTTP or HTTPS file URL. |
Send one source: data, file, or url. The examples below use the source mode appropriate for this format.
Output options
Generate Python source containing a column dictionary and pd.DataFrame construction. The API returns code text, not a live DataFrame or a pandas execution result.
This output format does not expose additional options.
Conversion rules
| Case | Behavior |
|---|---|
| Mapping rule 1 | Ampersand-separated LaTeX cell text becomes a row; TeX commands are not evaluated. |
| Mapping rule 2 | Header names become dictionary keys and data rows are transposed into column lists. |
| Mapping rule 3 | Convert TeX-formatted numbers and math expressions to plain values before analytical code generation; no TeX evaluation occurs. |
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
- Header names become dictionary keys and each column becomes a list of quoted values.
- Numbers and dates are not restored as pandas dtypes automatically; cast them in your analysis code.
- Review Python string escaping before running code containing quotes, slashes or newlines.
When to use this API
This conversion in practice
Use a LaTeX tabular dataset as the starting dataset for a Python notebook or analysis-test fixture. Remove presentation macros and simplify merged columns before exporting plain cell values.
pandas DataFrame code
Prepare a small reproducible input fixture for a Python analysis notebook.
Responses and errors
| HTTP status | Description |
|---|---|
200 | text/plain; charset=utf-8 |
400 | Invalid input or conversion parameters. |
402 | Insufficient credits for this request. |
403 | Missing or invalid API key. |
413 | The input exceeds the configured request limit. |
415 | Unsupported input media type. |
429 | Rate limit exceeded. |
500 | The conversion could not be completed. |
503 | The renderer is unavailable or the request timed out. |
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.

This page documents v2, which returns the output directly. API v1 wraps the result in a JSON envelope. Check the overview before changing an existing integration.
