Converters

Converters are the connectors that link different parts of your workflow together. Anyone who has had to feed a CSV export into a JSON API, paste tabular data into Markdown, drop a Unix timestamp into a human-readable date, or move a recipe from Fahrenheit to Celsius knows the friction of opening a new tab, finding a half-working tool, and praying it doesn't mangle the data. This category brings together 17+ converters that all run in your browser, never upload your data, and handle the common edge cases (UTF-8 BOM, quoted CSV fields, escaped Markdown characters, leap-year dates) correctly.

The collection covers data format conversions (CSV ↔ JSON, JSON ↔ XML, JSON ↔ YAML, Markdown ↔ HTML, Markdown to PDF, Excel to JSON), text encoding (text ↔ Base64), generators (QR code from text or URL, barcode), date and time conversions (Unix timestamp ↔ readable date in any timezone, time zone math, duration converter), and physical-unit converters (temperature, length, weight, generic unit converter that handles dozens of categories). Each tool focuses on a single conversion task, so the interface stays simple: paste in, click convert, copy or download out. Bookmark the ones that fit your workflow and you'll stop reaching for half-trusted converters scattered across search results.
