Code Generators

Generate a .env template from a JSON object or "key: value" text — keys become UPPER_SNAKE_CASE, values are serialized without quotes.

Generate a .gitignore file by selecting your language and frameworks. Templated from GitHub\'s gitignore repo.

Convert a base64 data URI into a viewable, downloadable image, or turn an image file into a base64 data URI. Auto-detects PNG, JPEG, GIF, WebP and SVG.

Convert CSV, TSV or semicolon-separated files into JSON with optional type inference. Handles quoted fields, embedded commas and newlines. No upload.

Parse a curl command and generate browser or Node fetch() code using async/await — methods, headers, JSON bodies, cookies and basic auth included.

Parse a curl command and generate a runnable Python script with requests or httpx — method, headers, JSON and form bodies, cookies, auth and TLS options.

Scaffold a docker-compose.yml with services, ports, volumes, and environment variables from a simple form. Runs entirely in your browser.

Escape text and code into HTML entities (ampersand, angle brackets, quotes) and unescape it back. Handy before pasting code into pre or code blocks.

Convert JSON to XML or XML to JSON with a single click. Handles nested objects, arrays, attributes, and text nodes. Runs entirely in your browser.

Convert a JSON Schema (draft-07) into TypeScript interfaces and type aliases — properties, required, enums, unions, $refs and nested objects. No upload.

Convert a JSON array of objects into CSV — columns are the union of all keys, missing values stay blank, and rows use CRLF line endings per RFC 4180.

Convert a JSON sample into a Python dict literal — valid identifier keys stay bare, invalid keys get quoted, and true/false/null become True/False/None.

Generate CREATE TABLE and INSERT statements from a JSON array. Infers column types and safely escapes string values. Runs entirely in your browser.

Validate JSON Schemas for LLM structured output. Presets for OpenAI, Anthropic and Gemini. Preview mock data and check real model output. No upload.

Format messy SQL into clean, indented statements or minify it to a single line. Handles strings, comments, identifiers and subqueries. No upload.

Validate SQL syntax for MySQL, PostgreSQL, SQLite, and SQL Server instantly. Paste your SQL and get error locations and explanations. 100% browser-based.
