Format, validate, and convert code and data: JSON, SQL, XML, YAML, HTML, and C#.
Data
Format, validate, and minify JSON in your browser. Paste it, upload a file, or load it from a URL. Errors show the exact line and column.
Open tool →C# / .NET
Paste JSON and get C# model classes or records, ready for System.Text.Json or Newtonsoft.Json. Nested objects, arrays, nullable types, dates, and GUIDs are inferred for you.
Open tool →SQL
Format and beautify SQL queries for SQL Server (T-SQL), PostgreSQL, MySQL, Oracle, and more. Set the indentation, keyword case, and layout, and get the exact line of any syntax error.
Open tool →Data
Format, validate, and minify XML (config files, .csproj, SOAP, RSS) in your browser. Entities, CDATA, and mixed content are kept exactly as written, and errors show the line and column.
Open tool →Data
Format and validate YAML (docker-compose, Kubernetes, GitHub Actions) without losing comments, or convert YAML to JSON. Errors show the exact line and column.
Open tool →Web
Beautify HTML pages and fragments without changing how they render. Inline spacing, <pre>, and scripts stay intact, and embedded CSS and JavaScript can be formatted too.
