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.
