Convert text to its ASCII or Unicode decimal character codes, separated by spaces or commas

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 text to its ASCII or Unicode decimal character codes, separated by spaces or commas, so you can move between the representations instantly and inspect exactly what your data contains.

Why this conversion is useful

Every character has a numeric code, and converting text to those codes reveals what it is made of at the character level, which is useful for debugging, low-level processing, or understanding an encoding. 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

The output lists each character’s decimal code in order. 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.

Frequently Asked Questions

What does it produce?

The decimal ASCII or Unicode code for each character in your text, separated by spaces or commas.

When is this useful?

For debugging, low-level text processing, and understanding what characters a string actually contains, including invisible ones.

Does it handle Unicode?

Yes. Characters beyond ASCII get their Unicode code point, so any character converts to its numeric value.

Is the conversion reversible?

Yes. It works both ways, so you can round-trip data to confirm nothing was lost in the conversion.

Is my text uploaded?

No. The conversion runs entirely in your browser.

Privacy & Security

All processing happens locally in your browser — nothing is uploaded.
