Convert ASCII or Unicode decimal character codes back into readable text, accepting space, comma or other separators

Encoding text between forms is a routine task in programming and debugging, and doing it by hand is slow and error-prone. This tool converts ASCII or Unicode decimal character codes back into readable text, accepting space, comma or other separators, so you can move between the representations instantly and inspect exactly what your data contains.

Why this conversion is useful

When you have a list of character codes, from a log, a dump, or the output of another tool, turning them back into text is how you read what they represent. Seeing text in a different representation is often how you diagnose an encoding problem, spot an unexpected character, or prepare data for a system that expects a particular form. The conversion is exact and reversible, so you can round-trip data to confirm nothing was lost.

Instant, and local

It accepts codes separated in various ways and reconstructs the text. It runs entirely in your browser, so nothing you paste is uploaded and the result is yours to copy straight into a project, which lets you work on private code and data without anything leaving your machine.
