<!-- Awaiting conversion... -->CAPABILITIES
Built for ETL pipelines, system integrations, API adapters, and any workflow where data needs to move cleanly between formats without manual transformation.
Convert between JSON, XML, YAML, and CSV in both directions through a consistent REST endpoint. No separate tools needed for each format pair.
The API preserves nesting, arrays, attributes, and data types during conversion. Output reflects the structure of the input rather than flattening or losing hierarchy.
Supports JSON, XML, YAML, and CSV as both input and output. Use the correct endpoint for each conversion pair to get clean, well-formed output in the target format.
Built for throughput. POST your payload and receive the converted output in the response body. Suitable for real-time API calls and batch processing pipelines at scale.
Each format conversion returns well-formed, valid output. JSON arrays, XML namespaces, YAML anchors, and CSV quoting are all handled correctly without manual post-processing.
No SDK required. Send a POST with your data payload and receive the converted format in the response. Integrate from Python, Node.js, PHP, Go, or any HTTP client in minutes.
USE CASES
From ETL pipelines to system integrations and config management, the API handles format transformation so your code does not have to.
When pulling data from a legacy XML source and loading it into a JSON-based API or database, the conversion step is often the most fragile part. This API handles format transformation reliably so your pipeline does not need a custom parser.
Remove brittle custom parsers from your ETL pipeline
Handle format conversions at scale with a consistent endpoint
Reduce engineering time spent on data transformation logic
Support multiple conversion pairs from a single integration point
Writing your own format converters is error-prone and requires ongoing maintenance. This API gives your pipeline a reliable, maintained conversion service.

FAQ
Which data formats does the API support?
The API supports JSON, XML, YAML, and CSV as both input and output formats. Use the correct endpoint for the conversion pair you need — for example, /convert/json/to/xml or /convert/xml/to/json.
Is the conversion bi-directional?
Yes. You can convert in both directions between supported format pairs. Each direction uses its own endpoint so the API can apply the correct serialisation rules for the target format.
Does the API preserve data structure and nesting?
Yes. The conversion preserves the hierarchical structure of the input including nested objects, arrays, and attributes. The output reflects the structure of the source data rather than flattening it.
How do I send the data to the API?
Send a POST request with your data in the request body. For JSON input, send it as a JSON body. For XML or YAML, send it as a plain text or appropriate content-type body. The API returns the converted format in the response.
Can I use this in a batch processing pipeline?
Yes. The endpoint is stateless and designed for programmatic use. You can call it in loops, ETL scripts, or queue consumers to convert data at scale — one record or document per request.
Does the API handle XML attributes and namespaces?
Yes. XML-specific features like element attributes and namespaces are handled correctly during conversion. The output preserves XML conventions rather than stripping metadata that would cause downstream parsing errors.
Can I convert CSV to JSON or JSON to CSV?
Yes. CSV is supported as both input and output. When converting CSV to JSON, each row is mapped to a JSON object with the header row as keys. When converting JSON to CSV, array-based JSON structures are flattened to rows.
Is there an SDK required?
No SDK is required. The API uses standard HTTP POST requests and returns the converted data as the response body. It works from any language, framework, or automation tool that can make HTTP requests.
