JSON and XML are structured formats used by apps and APIs, and Markdown is a simple way to write formatted text.

How Excel to CSV keeps your documents and data files private
Most online converters upload your file to their server, process it there and send it back. That costs time, uses your data pack and means a copy of your file sits on someone else’s computer. Excel to CSV works differently: the page loads the tool into your browser, and your documents and data files are processed by your own phone or computer. The file never travels over the internet, so it cannot be leaked, stored or misused.
Using Excel to CSV on your phone
Excel to CSV is designed for small screens. Buttons are large, options are simple, and downloads save directly to your phone storage. On iPhone, downloaded files appear in the Files app under Downloads; on Android they go to the Downloads folder.
