Convert JSON to TypeScript, Markdown, and other developer formats — processed privately in your browser.
- JSON to TypeScript Converter
Turn a JSON example into TypeScript interfaces — nested objects become named interfaces, arrays of objects merge with optional keys, and mixed types become unions.
- JSON to Markdown Table Converter
Convert a JSON array of objects into a Markdown table — one row per element, columns from the union of keys, pipes and line breaks escaped.
- JSON to YAML Converter
Convert JSON to clean YAML — for Kubernetes manifests, CI pipelines, docker-compose and config files.
- YAML to JSON Converter
Convert YAML to JSON with a safe parser — anchors and merge keys expanded, no code execution, errors reported with line and column.
- JSON to XML Converter
Convert JSON to XML — objects become elements, arrays repeat a singularized child element, and special characters are escaped.
- XML to JSON Converter
Convert XML to JSON — attributes become "@" keys, repeated elements become arrays, and numeric or boolean text optionally becomes real types.
- JSON to CSV Converter
Convert a JSON array of objects to CSV for Excel and Google Sheets — RFC 4180 quoting, nested objects flattened into dotted columns, comma/semicolon/tab delimiters.
- JSON to JavaScript Object Converter
Convert JSON into a JavaScript object literal — identifier keys unquoted, your choice of quote style, optional trailing commas and declaration prefix.
- JSON to PHP Array Converter
Convert JSON into a PHP array literal — short [] or array() syntax, single-quoted escaped strings, the exact structure json_decode($json, true) would produce.
- JSON to Python Dictionary Converter
Convert JSON into a Python dict literal — true/false/null become True/False/None, strings are escaped for Python, and the result is valid Python 3 as-is.
- JSON to Java Class Converter
Generate Java classes from a JSON example — POJOs with getters/setters, Java 16+ records, or Lombok style.
- JSON to C# Class Converter
Generate C# classes or records from a JSON example — PascalCase properties with [JsonPropertyName] attributes for System.
- JSON to SQL Insert Converter
Convert a JSON array of objects into SQL INSERT statements — MySQL, PostgreSQL/ANSI or SQL Server quoting, multi-row or per-row, nested objects flattened into columns.
- JSON to HTML Table Converter
Convert a JSON array of objects into a semantic HTML table — thead/tbody, scoped headers, optional caption and CSS class, with every value HTML-escaped for safety.
- JSON to URL Parameters Converter
Convert a JSON object into a URL query string — percent-encoded, with nested keys in bracket (PHP/Rails) or dot style, and null handling you control.
The same data, the shape you need
Data rarely stays in one format. The response you fetched as JSON needs to become TypeScript interfaces in your codebase, a table in your README, a class in your backend language. Converters here do those translations mechanically and honestly: what the input proves is converted; what it cannot prove (like optionality from a single sample) is flagged instead of guessed.
Growing set
TypeScript and Markdown tables are live now; YAML, XML, CSV and per-language class generators are planned next in this cluster. Each converter documents its edge cases — escaping rules, precision limits, naming conventions — on its own page, so you know exactly what you will get before you paste.
