What does this file converter support?
This browser-based converter is designed for text and structured data files. It supports practical conversions between plain text, CSV, JSON, XML, and Base64 formats without uploading your file to a server.
Best use cases
Use it to convert JSON arrays into CSV, turn CSV data into JSON, format plain text into Base64, decode Base64 into readable text, or transform simple XML into JSON and back.
It is especially useful for developers, analysts, QA teams, and anyone handling exports, logs, configuration files, or API data.
Private browser-based conversion
All conversion runs locally in your browser. Your file stays on your device, which makes the tool fast and suitable for private or internal text-based files.
