Explore JSON Tools
Choose an online JSON tool for the task at hand. RomitJSON brings common workflows together, from reading an API response and checking syntax to comparing documents and converting compatible data.
Format and Read JSON
- JSON Formatter organizes data with consistent indentation and line breaks.
- JSON Viewer helps explore JSON objects, arrays, and nested structures.
- JSON Tree Viewer focuses on expand-and-collapse navigation inside nested JSON.
- JSONPath Finder locates keys and values and runs JSONPath queries.
- JSON Validator checks whether JSON follows valid syntax and reports parsing issues.
- JSON Repair applies a limited set of transparent syntax fixes to JSON-like text.
- JSON Schema Validator checks JSON data against a Draft 2020-12 schema.
- JSON Schema Generator creates a Draft 2020-12 schema by inferring structure from sample data.
- JSON Editor lets you modify JSON content and review the result.
Compare and Optimize JSON
- JSON Minifier removes unnecessary whitespace from valid JSON.
- JSON Compare compares two JSON documents to identify structural and value differences.
Convert JSON to Other Formats
- JSON to CSV Converter transforms compatible JSON records into rows and columns.
- JSON to Excel Converter exports JSON records to a spreadsheet workbook.
- JSON to SQL Converter generates table definitions and data insert statements for SQLite, MySQL, and PostgreSQL.
- JSON to YAML Converter converts objects and arrays into YAML for supported workflows.
- JSON to XML Converter converts JSON structures using a typed XML mapping.
- JSON to TypeScript Converter generates interfaces or type definitions from sample JSON.
- JSON to Java Converter generates Java model classes and nested types from sample JSON.
- JSON to Python Converter generates nested TypedDict or dataclass models from sample JSON.
What Is JSON?
JSON, short for JavaScript Object Notation, is a lightweight text format used to represent structured data. It is widely used in web APIs, application settings, data exchange, and software development.
A JSON object stores information as key-value pairs, while arrays hold ordered collections of values. JSON supports strings, numbers, booleans, null, objects, and arrays.
{
"name": "Aarav",
"role": "Developer",
"active": true,
"skills": ["JavaScript", "JSON", "APIs"]
}
This example contains a name, role, active status, and list of skills. A formatter can make the structure easier to read, while a validator checks its syntax. Conversion tools can transform compatible data for other workflows.
Why Use Online JSON Tools?
Read complex data more easily
API responses and configuration files can contain deeply nested objects and arrays. Formatting and viewing tools help you inspect that structure without manually adding line breaks.
Find syntax errors
JSON has strict syntax rules. Property names and strings require double quotes, and trailing commas are not allowed. A validator can help identify errors before you use the data elsewhere.
Compare changes
When JSON changes between two versions, a comparison tool can help review the differences instead of reading both documents line by line.
Convert data for different workflows
Depending on the structure, conversion tools can prepare data for CSV, YAML, XML, or TypeScript definitions. Review the result against the requirements of the destination application.
Simplify everyday development tasks
From checking API responses to preparing sample data, focused JSON tools can reduce repetitive manual work during development and debugging.
Common JSON Syntax Mistakes
JSON is simple to read, but small syntax errors can make a document invalid.
Using single quotes
Invalid: {'name': 'Aarav'}
Valid: {"name": "Aarav"}
Adding a trailing comma
Invalid:
{
"name": "Aarav",
}
Valid:
{
"name": "Aarav"
}
Leaving a string unquoted
Invalid: {"city": Patna}
Valid: {"city": "Patna"}
Use the JSON Validator when you are unsure why a document is failing to parse.
