Convert Djot to reStructuredText

Turn Djot, a light markup language designed as a cleaner successor to Markdown, into reStructuredText, the documentation format of the Python ecosystem and Sphinx. FileChanger runs the document conversion in one call, no local tooling to install.

In the browser

Upload a file and download the result, no pipeline required. Open the converter.

One API call

POST the file with from=djot and to=rst, get the converted bytes back. Jump to the code.

From an agent

FileChanger ships an MCP server, so agents can run this conversion themselves. See the docs for setup.

Convert Djot to reStructuredText in code

The same call from any language: POST the file to /api/convert, the response body is the converted file.

curl -X POST https://filechanger.io/api/convert \
  -H "X-Api-Key: fc_your_api_key_here" \
  -F "file=@input.djot" \
  -F "from=djot" \
  -F "to=rst" \
  -o output.rst

import requests

with open("input.djot", "rb") as f:
    response = requests.post(
        "https://filechanger.io/api/convert",
        headers={"X-Api-Key": "fc_your_api_key_here"},
        files={"file": f},
        data={"from": "djot", "to": "rst"},
    )

response.raise_for_status()
with open("output.rst", "wb") as out:
    out.write(response.content)

const formData = new FormData();
formData.append("file", fileInput.files[0]);
formData.append("from", "djot");
formData.append("to", "rst");

const response = await fetch("https://filechanger.io/api/convert", {
  method: "POST",
  headers: { "X-Api-Key": "fc_your_api_key_here" },
  body: formData,
});

const output = await response.blob();

About Djot

Djot is a light markup language created by pandoc's author John MacFarlane as a cleaner, more parseable successor to Markdown. It fixes Markdown's ambiguities with a simpler spec, and is gaining adoption among people who care about predictable plain-text markup.

About reStructuredText

reStructuredText (RST) is the documentation format of the Python world, consumed by Sphinx to build the docs of Python itself and thousands of libraries. Its directive system supports cross-references, API docs, and multi-page manuals beyond what plain Markdown offers.

Frequently asked questions

How do I convert Djot to reStructuredText?

Upload your file in the browser converter and pick reStructuredText as the target, or POST it to /api/convert with from=djot and to=rst. The response body is the converted file.

Is converting Djot to reStructuredText free?

Yes. The free tier includes 2 GB of conversions per month, metered on input size. See pricing for the paid tiers.

Is there an API for Djot to reStructuredText conversion?

Yes, this whole conversion is one POST to /api/convert (the code examples above show it in five languages), plus an MCP server so AI agents can run it directly.
