Choose the JSON task before choosing the tool
Tool Factory connects each JSON task to a working canonical tool. Every tool page states whether processing stays in the browser or needs a network request, so users can choose a suitable path before providing data.
| Task | What it checks or changes | Use it when |
|---|---|---|
| Validate | Checks whether the input follows JSON grammar. | A parser rejects the document or the syntax is uncertain. |
| Format or minify | Changes whitespace and presentation without intending to change values. | People need readable JSON or a system needs compact JSON. |
| Compare | Finds differences between two JSON documents. | A configuration, response, or saved document changed. |
| Convert | Maps JSON values into another format and data model. | Another system needs CSV, XML, YAML, or another representation. |
| Canonicalize | Creates a deterministic representation under a defined scheme. | A signing or hashing workflow requires stable serialized bytes. |
How to complete this task
- Keep an unchanged source. Save the original document before formatting, repairing, or converting it.
- Validate the grammar. Resolve syntax errors before comparing values or converting formats.
- Run one focused transformation. Choose formatting, comparison, extraction, or conversion from the required outcome.
- Inspect semantic changes. Check numbers, null values, arrays, nested objects, and duplicate names after processing.
- Verify the receiving system. Test the final document with the application that will consume it.
Common use cases
API response troubleshooting
Validate and format a response before tracing a missing field or unexpected value.
Configuration review
Compare two versions and inspect the exact path of every material change.
Data exchange preparation
Convert JSON only after identifying how the target format handles types and nesting.
Evidence and standards
- RFC 8259: The IETF standard defines JSON as a text-based, language-independent interchange format with objects, arrays, and primitive values.
- ECMA-404: ECMA-404 provides the JSON syntax specification aligned with the IETF definition.
- RFC 6902: JSON Patch defines an ordered operation format for applying changes to a JSON document.
- RFC 7396: JSON Merge Patch defines a document-shaped format for describing selected JSON changes.
- RFC 8785: The JSON Canonicalization Scheme defines deterministic serialization for repeatable cryptographic processing.
Important limits
- Valid JSON can still contain incorrect, unsafe, or incomplete application data.
- Conversion can lose types, nesting, ordering assumptions, or numeric precision.
- Formatting does not validate a business schema unless the selected tool performs that separate check.
