Tips
JSON and XML only
This converter does not turn data into CSV, YAML, or TOML—ignore any dead UI that suggests otherwise.
Server round-trip required
Conversion POSTs your text to Toolomix. It is not a local-only transform.
Review structure after convert
XML attributes and JSON keys do not always map one-to-one.
Validate when unsure
Use Validate Format if available before converting malformed input.
JSON to XML on the server
Posts to ConvertJsonToXml and returns XML from Toolomix.
XML to JSON on the server
Posts to ConvertXmlToJson and returns JSON from Toolomix.
Paste-first workflow
Works on pasted text with optional size/time statistics in the UI.
What this tool does
JSON ⇄ XML Converter transforms pasted JSON into XML or pasted XML into JSON.
Both directions run on Toolomix servers. It does not convert CSV, YAML, or TOML.
How to use
Paste JSON or XML
Add well-formed text for the selected direction.
Confirm direction
JSON→XML or XML→JSON (swap if needed).
Convert on Toolomix
Submit so the matching ConvertJsonToXml or ConvertXmlToJson endpoint can process the text.
Review and copy
Check the structure, then copy the result.
Supported inputs and output
Input: pasted JSON or XML. Output: the other format from the Toolomix conversion endpoints.
CSV, YAML, and TOML are not supported conversion targets or sources in this tool.
Processing and privacy
Conversion is not browser-only. Your pasted content is sent to Toolomix for ConvertJsonToXml or ConvertXmlToJson.
See the Privacy Policy for how requests and logs are handled. Do not paste secrets you cannot send to the service.
Limitations
Known limits
- JSON⇄XML only—no CSV/YAML/TOML
- Requires a successful server response
- Not a lossless identity transform across all XML features
- Dead JS/UI for other formats is not functional
- Primary input is pasted text
Troubleshooting
If conversion fails, confirm the direction matches the input type and that the text is well-formed.
Network or server errors can fail even when the text looks fine—retry and read the on-page error.
Frequently Asked Questions
Is conversion done only in the browser?
No. Conversion POSTs your JSON or XML to Toolomix (ConvertJsonToXml or ConvertXmlToJson) and returns the result. It is not browser-only.
Can I convert CSV, YAML, or TOML?
No. Only JSON⇄XML is implemented. Any CSV/YAML/TOML UI or scripts are dead and not supported.
Does the conversion preserve every detail?
Structure is mapped as closely as practical, but JSON and XML differ (attributes, mixed content, etc.). Always review the output.
Can I convert XML back to JSON?
Yes. Switch direction (Swap Formats) and run ConvertXmlToJson via the server.
Do I upload a file?
The primary workflow is pasting text into the input area.
What do the statistics mean?
When shown, they reflect input/output size and processing time for that server conversion—not long-term storage metrics.
Why did conversion fail with valid-looking text?
The payload must be well-formed JSON or XML for the selected direction, and the Toolomix endpoints must respond successfully.
