About the Hex to Text
The decoder strips common notation before converting: whitespace, :, -, ,, ;, 0x, \x and %. So 48 65 6c 6c 6f, 48:65:6C:6C:6F, 0x48,0x65,0x6c,0x6c,0x6f and \x48\x65\x6c\x6c\x6f all decode to Hello. Upper and lower case digits are both accepted.
The bytes are decoded strictly as UTF-8. If they are not valid UTF-8 — for example a Latin-1 byte like e9 on its own, a truncated multi-byte sequence, or binary data such as an image header — you get an error instead of replacement characters, so you know the data is not plain text. An odd number of digits or a non-hex character is reported with the offending value.
Typical uses: reading hex dumps from Wireshark or xxd, decoding strings stored as hex in databases or logs, and checking what a \x-escaped string contains.
How to use it
- Paste the hex bytes in any common notation.
- Read the decoded text in the output pane.
- Fix any reported invalid digit or odd length.
- Copy the text, or use ⇄ Swap to re-encode it.
