Converters

Free online converters for data formats, units, colors, currencies, images, and more. Convert JSON, CSV, XML, YAML, timestamps, number bases, and units — all instant and browser-based.

Data Format Converters

Modern development involves dozens of data formats — JSON for APIs, CSV for spreadsheets, XML for enterprise systems, YAML for configuration, and more. Converting between these formats manually is tedious and error-prone. ToolStand converters handle all these transformations instantly in your browser. Paste your data in one format, get the equivalent in another. No data leaves your device.

Unit and Measurement Converters

The world uses multiple measurement systems, and converting between them is a daily necessity. The unit converter handles length, weight, temperature, area, volume, and speed — all in one tool. The currency converter fetches live exchange rates and shows 7-day trends. The timezone converter shows current local times across cities worldwide.
