Whitespace & Trim Tools

Case Converter

Convert text or an identifier into every common naming style at once — camelCase, snake_case, kebab-case, and more. Recognizes word boundaries in camelCase/PascalCase, acronyms (XMLParser → XML + Parser), and around digits.

Text Diff

Compare two texts line by line — what was added, removed, or changed, with word-level highlighting inside changed lines.

Regex Tester / Find & Replace

Test regular expressions against real text: highlighted matches with parsed capture groups, or replace matches with new text.

Sort & Dedupe Lines

Sort lines of text alphabetically, remove duplicates, empty lines, and extra whitespace.

String Escape

Escape text into a string literal (quotes, backslash, control characters) for pasting into code, or unescape it back.

CRLF ↔ LF Converter

Convert line endings between Windows (CRLF), Unix/macOS (LF), and classic Mac (CR), with mixed-ending detection.

Scrypt Hash + Verify

Hash passwords with scrypt (RFC 7914, memory-hard KDF), with verification against an existing hash.

Email Header Analyzer

Parse raw email headers (View Source / Show Original) — key fields, the Received chain with hop timings, SPF/DKIM/DMARC, From/Reply-To spoofing indicators.

Placeholder Image Generator

Generate a placeholder image of a given size for mockups and layout.

JSON Path Extractor / Flatten

Flatten nested JSON into a flat "path: value" list, and rebuild it back into a nested structure (Unflatten). Path notation matches JSONPath/JSON Diff: store.book[0].price.

JSON ↔ YAML / CSV / XML / TOML

Convert JSON to YAML, CSV, XML, or TOML and back — entirely in the browser, no libraries.

Data URI / Base64 image

Encode an image into a Data URI (data:image/…;base64,…) for embedding in CSS/HTML, and decode a Data URI or raw Base64 back into a file — all in your browser.
