Octal to String

Convert octal values back to readable text instantly — with validation that flags invalid digits. Free, instant, client-side octal to text decoder.

Example

Input

110 151 041

Output

Hi!

The exact inverse of the octal encoder. Digits 8 and 9 are rejected with a message rather than silently decoded, since they cannot appear in valid octal.

Common Use Cases

Decoding C and shell escapes

Convert the octal escapes found in source code and core dumps back into the characters they represent.

Reading legacy data

Decode octal-encoded fields from older Unix tools and file formats.

Frequently Asked Questions

What input format is expected?
Space-separated octal values using digits 0–7, like "110 151" which decodes to "Hi". Any token containing 8, 9, or letters is reported as invalid instead of producing wrong output. String to Octal generates input in exactly this format.
How is octal different from hex encoding?
Both represent the same byte values in different bases — octal uses digits 0–7 (base 8), hex uses 0–F (base 16). Hex is more common today; octal survives mainly in Unix permissions and escape sequences. For the hex equivalent of this decoder, use Hex to Text.
Is my data private when I use this tool?
Yes. This tool runs entirely in your browser using client-side JavaScript — nothing you type is transmitted to, logged by, or stored on any server. You can safely process confidential text, tokens, or code.
