QUICK ANSWER
Is it possible to convert GDCB to TXT?
No - not a direct conversion.

GDCB is a file scrambled by the GandCrab ransomware, not a text document, so it can't be turned into a readable .txt. If your original file was actually a text file, run a free GandCrab decryptor and it comes back as the exact .txt it was before.

Why convert GDCB to TXT?

A .gdcb file is ciphertext produced by GandCrab's Salsa20 encryption - opening it in a text editor shows only unreadable binary. There is no meaningful path from encrypted data to a plain .txt except reversing the encryption, which restores whatever the file originally was (its real extension is preserved beneath the .gdcb suffix).

Quality & what to watch

  • Do not expect a text conversion - a .gdcb file is encrypted binary and will look like garbage in Notepad until it is decrypted.
  • The GandCrab ransom note itself is a separate plain-text file named GDCB-DECRYPT.txt; it is not your encrypted data.
  • Recovery depends on the decryption keys being available for your GandCrab version; unsupported variants may be unrecoverable without a backup.

Frequently asked questions

Why can't I just open a .gdcb file in Notepad?
Because it is encrypted binary, not text. Notepad shows random characters until the file is decrypted back to its original form.
What is GDCB-DECRYPT.txt?
That is the ransomware's ransom note - a real text file left by GandCrab. It is not one of your encrypted files.
How do I get a text file back from .gdcb?
Run a free GandCrab decryptor (Bitdefender, ESET or No More Ransom). If your file was originally a .txt, it is restored exactly as it was.
Can any converter turn .gdcb into .txt?
No converter can. Only decryption with the correct key reverses GandCrab encryption and recovers the original file.
