What this tool does
This page helps you switch between JSON, XML and YAML so integrations, debugging sessions and documentation handoffs are easier to manage in one place.
- Converts structured data between JSON, XML and YAML formats in the browser without requiring any external tooling.
- Preserves the data structure during conversion so field names, nesting and values translate consistently between formats.
- Helps developers bridge format mismatches during integration work, debugging sessions and documentation preparation.
How to use it
- 1
Paste your data in the source format: JSON, XML or YAML.
- 2
Select the target format you want to convert to.
- 3
Review the converted output and confirm values and structure look correct.
- 4
Copy the result into your API client, config file, documentation or integration code.
Example
A developer has an API returning JSON but needs to pass the same data to a legacy service expecting XML and converts it in seconds without writing a transform script.
{"service": "billing", "version": "2", "active": true}<root><service>billing</service><version>2</version><active>true</active></root>Use cases
- Converting API payloads between formats during integration work.
- Preparing the same data for docs, config files or tooling that expects another format.
- Checking how a structured payload looks after format conversion.
Common mistakes
Expecting lossless round-trip conversion
Some data types have no direct equivalent in all three formats. Boolean, null and numeric types can serialise differently depending on the target format.
Converting deeply nested XML to YAML blindly
XML attributes and mixed content nodes do not have a universal YAML representation. Review the output when converting from XML.
Using converted output without validation
Always validate the result in the target format after conversion. Structure usually transfers cleanly but edge cases can produce unexpected output.
FAQ
Can I convert between all three formats bidirectionally?
Yes. JSON, XML and YAML can be converted in any direction.
Are there data types that do not convert cleanly?
Yes. XML attributes, mixed content, YAML anchors and JSON null values all have quirks when crossing formats.
Does this tool upload my data?
No. Conversion runs locally in the browser.
Can I use this for Kubernetes or CI config?
It helps convert between formats, but the resulting YAML should still be validated against the target schema or manifest spec.
What happens if my input is not valid in the source format?
The converter will report a parse error. Validate and format the input first using the dedicated JSON, XML or YAML formatter.
Privacy and security
- Conversion stays in the browser during processing.
- No structured payload is uploaded to an external conversion service.
- That matters when the input includes internal routes, identifiers or operational data.

Convert the payload locally, then validate or format the result if the integration still needs cleanup.
