JSON looks small, but real work usually combines three separate problems: the text must be valid syntax, it must represent the intended structure, and the receiving system must preserve its meaning. This path separates those layers so you can find the actual fault before transforming data.
Choose your starting point
- If you have an error, validate first and correct the first diagnostic before moving on.
- If the document is valid but hard to read, format it without changing strings or numbers.
- If an API rejects the content, check whether it expects an object, an array, or a more specific contract.
- Before conversion, review null values, large numbers, and nested structures.
Recommended workflow
Confirm the syntax first. Inspect the shape of the data next, and only then convert it to YAML or CSV. This order prevents a converter from being blamed for a problem already present in the source and makes it easier to compare the output with a known input.
The tools on this page process content locally. Validation alone cannot decide an API’s business rules: valid JSON may still be missing required fields or contain values and types that the destination does not accept.
