# XML To HTML Guide
> Transform XML with XSLT and use the generated HTML in your own workflows.
Use `POST /convert/xml-to-html` when you already have XML data and an XSLT stylesheet that describes the output format.
## Request Modes
| Mode | Content type | Fields |
| -------------- | --------------------- | --------------------- |
| Inline payload | `application/json` | `xml`, `xslt` |
| File upload | `multipart/form-data` | `xmlFile`, `xsltFile` |
## Output
The endpoint returns:
* `text/html` by default
* JSON metadata when you send `Accept: application/json`
## Limits
* XML is limited to **5 MB**
* XSLT is limited to **1 MB**
* Credit cost is **1**
## Typical Use Cases
* Converting structured business XML into email-ready or browser-ready HTML
* Generating HTML first, then sending the result into `POST /convert/html-to-pdf`
* Keeping layout logic in XSLT while your application only passes data
## JSON Example
```json theme={null}
{
"xml": "INV-1001",
"xslt": "
"
}
```
