What is JSON validation?

JSON validation checks if your JSON data follows the correct syntax rules. A valid JSON must have properly matched brackets, quotes around strings, and correct comma placement. This tool instantly validates your JSON and highlights any errors. You can also use our Diff Tool to compare JSON structures.

How do I validate JSON schema?

JSON Schema is a vocabulary that allows you to validate the structure and content of JSON data. Paste your JSON Schema in the schema tab, then validate your data against it. The validator will show if your data matches the schema requirements. For pattern matching, try our Regex Tester .

JSONPath is a query language for JSON, similar to XPath for XML. It allows you to extract specific values from JSON data using path expressions. For example, "$.users[0].name" extracts the name of the first user. Use regex patterns for advanced text extraction.

Can I convert JSON to YAML?

Yes, this tool supports bidirectional conversion between JSON and YAML formats. Simply paste your data and switch between formats using the format selector. The conversion preserves your data structure perfectly. You might also need our Base64 Encoder for API data transmission.

Is my data secure when using this validator?

Yes, absolutely. All validation happens locally in your browser. Your data never leaves your device or gets sent to any server. The tool works completely offline once loaded. For data integrity verification, use our Hash Generator .
