ASCII Converter
ASCII Converter encodes text into ASCII values and decodes ASCII values back to readable text. It supports common developer formats such as decimal, hexadecimal, binary and octal. Use it when inspecting protocol bytes, debugging encoded payloads, teaching character encodings or converting small snippets for tests.

How to use
Enter text and choose Encode to view the ASCII values, or paste ASCII numbers and choose Decode. Select the radix and separator that match your input. The tool is best for small to medium snippets where you want to inspect exact character values quickly.
Example: Example: encode `ABC` to decimal values `65 66 67`, or decode those values back into the original text.
