JSON & Data Interchange
JSON (JavaScript Object Notation) is the universal language of web APIs and modern data exchange. Our JSON tools help you format and validate JSON documents, convert between JSON and CSV formats, and work with data interchange patterns. All processing happens client-side, so sensitive API payloads and configuration data never leave your browser. These tools are essential for developers building APIs, data analysts preparing datasets, and anyone working with JSON-formatted configuration files.

Frequently Asked Questions
Why is JSON the standard for data interchange?
JSON is lightweight, human-readable, language-independent, and natively supported by JavaScript. It has become the dominant format for web APIs, surpassing XML, because it is faster to parse, more compact, and maps directly to programming language data structures like objects and arrays.
What is the difference between JSON and CSV?
JSON supports nested data structures, multiple data types (strings, numbers, booleans, arrays, objects, null), and is self-describing with named keys. CSV is tabular, flat, and more compact for simple datasets, but lacks type information and cannot represent hierarchical data. Our JSON to CSV converter handles the conversion between these two formats, flattening nested JSON into columns.
Can JSON contain comments?
The JSON specification (RFC 8259) does not support comments. If you need annotations in configuration files, consider using JSON5, YAML, or a pre-processing step that strips comments before passing to the JSON parser.
