Document opens but displays random symbols, squares, or gibberish characters instead of text

What's actually wrong

Gibberish on screen has two very different causes, and it's worth 60 seconds to tell them apart. Most often the text is perfectly fine and only the display is wrong: the document uses a font you don't have installed (Microsoft's cloud font Aptos is a frequent offender on older Windows), or the file was opened through Word's "Recover Text from Any File" converter, which renders any intact file as symbol soup. True corruption — where binary garbage has replaced the text — is rarer, and if the underlying XML is damaged the recoverable amount varies, so diagnose before panicking.

Free fixes — try these first

1. Rule out fonts first: press Ctrl+A to select everything and switch the font to Arial or Times New Roman. If real words appear, the file was never damaged — install the missing font (e.g., download Aptos from Microsoft) and you're done.
2. Check the converter trap: in Word go to File → Open → Browse and look at the file-type dropdown next to the file name. If it says Recover Text from Any File (*.*), set it back to All Word Documents and open the file again — that converter deliberately renders intact files as symbols.
3. Check what the file really is: open the .docx in Notepad. If the first two characters are PK it's a genuine docx archive — go to the next step. If you see readable text with {\rtf or HTML tags instead, the file is mislabeled: rename the extension to .rtf or .html and it will open normally.
4. Open and Repair: File → Open → select the file → arrow beside Open → Open and Repair; if that fails, try opening it in LibreOffice Writer, which tolerates more damage.
5. Rule out your Word install: run winword /safe (Windows key + R) and open the file there; if it displays correctly, an add-in or corrupt Normal.dotm on your machine is scrambling the display, not the file.

If the free fixes fail

If Notepad shows no PK header and no recognizable format, or the archive is damaged inside, free methods hit a wall — our analyzer detects what the file actually is (mislabeled formats are fixed free) and, for genuinely corrupted archives, shows an honest percent-recovered preview rather than a promise.
