Frequently Asked Questions

Why does my text show weird characters like ’ or é?

This is called mojibake - it happens when text encoded in one format (like UTF-8) is read as another (like Windows-1252). Upload your file here to detect the correct encoding and convert it.

What file types are supported?

Any text-based file including .txt, .csv, .html, .xml, .json, .log, .sql, and source code.

Note: Microsoft Word (.doc/x) and Excel (.xls/x) files are binary and cannot be converted directly — please export them as "Plain Text" or "CSV" first.

How accurate is the encoding detection?

Detection uses statistical analysis and works best with files containing 100+ characters. The confidence percentage indicates how certain the detection is. UTF-8 and ASCII are detected with very high accuracy.
