Suggestions

Better conversion results

Detection is probabilistic Encoding detection is an estimate, especially for short files.
BOM is explicit A BOM is a strong clue for UTF-8/UTF-16 files.
Binary files are flagged Office files are ZIP/binary packages, so text encoding may not apply.
Use with encoding fixer After detection, use CSV Encoding Fixer to save CSV as UTF-8.
Check output before sharing Open the downloaded file once to confirm layout, text, image quality, or password settings.
