Things to check before integrating
Before you integrate
Move required attributes into explicit fields and flatten repeated nested groups before sending XML.
Before you integrate
Multiple rows repeat top-level keys and are not valid TOML as a whole; restructure into tables or arrays of tables and validate escaping.
Code examples
These examples send the sample as multipart/form-data and save the returned bytes unchanged. Set TABLECONVERT_API_KEY in your environment.
XML to TOML API · cURL
curl --fail-with-body --max-time 40 \
'https://api.tableconvert.com/v2/convert/xml-to-toml' \
--header "Authorization: Bearer $TABLECONVERT_API_KEY" \
--form-string 'data=<?xml version="1.0" encoding="UTF-8" ?>
<dataset>
<record><name>frontend</name><mode>production</mode><retries>3</retries></record>
<record><name>worker</name><mode>development</mode><retries>1</retries></record>
</dataset>' \
--output 'xml-to-toml.toml'Requires cURL. Download the sample input first when this example uploads a file.
XML to TOML API · Python
import os
from pathlib import Path
import requests
endpoint = "https://api.tableconvert.com/v2/convert/xml-to-toml"
headers = {"Authorization": "Bearer " + os.environ["TABLECONVERT_API_KEY"]}
fields = {
"data": (None, "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>\n<dataset>\n <record><name>frontend</name><mode>production</mode><retries>3</retries></record>\n <record><name>worker</name><mode>development</mode><retries>1</retries></record>\n</dataset>"),
}
response = requests.post(endpoint, headers=headers, files=fields, timeout=40)
response.raise_for_status()
Path("xml-to-toml.toml").write_bytes(response.content)Requires Python 3 and requests. Install it with pip install requests.
XML to TOML API · Node.js
import { writeFile } from "node:fs/promises";
const form = new FormData();
form.set("data", "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>\n<dataset>\n <record><name>frontend</name><mode>production</mode><retries>3</retries></record>\n <record><name>worker</name><mode>development</mode><retries>1</retries></record>\n</dataset>");
const response = await fetch("https://api.tableconvert.com/v2/convert/xml-to-toml", {
method: "POST",
headers: { Authorization: "Bearer " + process.env.TABLECONVERT_API_KEY },
body: form,
signal: AbortSignal.timeout(40_000),
});
if (!response.ok) {
throw new Error("HTTP " + response.status + ": " + await response.text());
}
await writeFile("xml-to-toml.toml", Buffer.from(await response.arrayBuffer()));Requires Node.js 20 or later with built-in fetch, FormData and Blob.
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
The importer treats each direct child of the document root as a record and its child elements as fields. It is a record extractor, not a general XML schema or XSLT transformation.
| Parameter | Type | Default | Description |
|---|---|---|---|
data | string | — | Inline XML table content. Choose one of data, file or url. |
file | binary | — | Upload a xml 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 quoted TOML-style key-value assignments from columns. Multiple records currently repeat top-level keys, so multirow output must be restructured before TOML parsing.
This output format does not expose additional options.
Conversion rules
| Case | Behavior |
|---|---|
| Mapping rule 1 | Root-level child records supply rows, and their child element names supply the union of columns. |
| Mapping rule 2 | Header names become assignment keys and each row emits another set of quoted assignments. |
| Mapping rule 3 | Select child elements that should become settings keys and move any required attributes into fields before conversion. |
How the input is read
- Use a root element containing repeated record elements with child-element fields.
- Cell values use element textContent; attributes and deep tree structure are not emitted as separate columns.
- Repeated field names within one record overwrite earlier values; normalize repeating groups first.
- Review namespace-prefixed names before generating code identifiers or a new schema.
How the output is written
- Headers become keys and each row emits an assignment for each column.
- TOML forbids duplicate keys in one table; wrap multiple records into reviewed array-of-table sections manually.
- Validate key syntax, quote escaping and newlines; this endpoint is a configuration-text starting point.
When to use this API
This conversion in practice
Use a record-oriented XML export as the starting dataset for a configuration draft that will be reorganized into valid TOML. Move required attributes into explicit fields and flatten repeated nested groups before sending XML.
TOML key-value draft
Draft a single-record configuration or a multirow template to restructure into TOML tables.
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.
