Worth knowing
- Can it decode JWTs? Yes. Paste the middle part of the token (between the two dots) to read its payload. The signature is not verified.
- Why do I get a “binary data” message? The string decoded correctly, but the result is not text. It is probably an image or another file.
- Do I need to add = padding? No. Missing padding is added automatically.
- Works on any text column, not only Text Input's: pick it under Text column. Tick Generate New Column to keep the original next to the result.
