ASCII to Text
About the ASCII to Text Converter
The ASCII to Text Converter takes ASCII numeric codes (decimal, hex, octal, or binary) and turns them back into readable text. Developers debugging string-handling bugs, security analysts decoding network captures, students learning low-level computer science, and curious users reading raw error logs all rely on this reverse conversion to translate numeric character codes into the letters and punctuation they represent.
How ASCII to text works
Every printable character has a fixed ASCII number between 32 and 126 (plus some control codes). The converter reads your space- or comma-separated numbers, looks each one up in the ASCII table, and assembles the corresponding characters in order. It accepts decimal (65), hexadecimal (0x41 or 41), octal (101), and binary (01000001) — all of which mean the letter "A".
How to use it
- Paste your ASCII codes into the input box.
- Optionally tell the converter the base if it can’t auto-detect (decimal vs hex vs binary).
- The decoded text appears instantly.
- Copy the readable result with one click.
Common use cases
Reading raw byte sequences from packet captures, decoding hex-dumps of crash reports, recovering text from log files where strings were saved as numeric codes, solving CTF challenges that hide flags in ASCII number sequences, and verifying that an encoded string round-trips correctly back to the original.
Privacy and reverse operation
Conversion runs entirely in your browser using native JavaScript String.fromCharCode. Your numbers and text never leave your device. To go the other way and convert text into ASCII numbers, use our companion Text to ASCII tool.
