Tools
All tools run entirely in your browser. Nothing is uploaded or sent to a server.
Formatters
JSON Formatter
Format, minify, and validate JSON online. Paste API responses or config files — all processing stays in your browser.
YAML Formatter
Format and validate YAML in your browser. Fix indentation issues and confirm structure before deploy.
CSV Converter
Convert CSV to JSON or JSON arrays to CSV in your browser. Handy for spreadsheets, imports, and quick data checks.
ENV Formatter
Normalize, sort, and dedupe .env-style key=value files in your browser. Keep environment files consistent.
JWT Decoder
Decode JWT header and payload in your browser. Signature is not verified — for inspection and debugging only.
Data Processing
JSON Escape & Unescape
Escape text for use inside a JSON string, or unescape a JSON string back to plain text. Handles quotes, backslashes, newlines, control characters, and Unicode. Runs in your browser.
JSON Diff
Compare two JSON documents side by side. See added, removed, and changed fields for API responses — all in your browser.
Log Sanitizer & Secret Redaction
Sanitize logs and JSON before sharing them. Detects and redacts emails, IPs, JWTs, bearer tokens, API keys, and passwords in your browser — nothing is uploaded.
Markdown to Plain Text
Strip Markdown and AI chat formatting — headings, bold, bullets, links, and code fences — and get clean text you can paste into Word, email, or a CMS. Runs in your browser.
Markdown Table ↔ CSV
Convert a Markdown table to CSV for Excel or Google Sheets, or turn CSV, TSV, and spreadsheet data into a Markdown table. Handles quotes, commas, and escaped pipes. Runs in your browser.
HTML to Markdown
Convert HTML to Markdown in your browser. Headings, lists, tables, links, images, and code blocks. The HTML is parsed inertly and never rendered, and unsafe link schemes are dropped.
