Text to ASCII

Updated:

Convert text to ASCII character codes in decimal, hex, binary or octal, with strict validation because ASCII defines only the 128 characters numbered 0 to 127.

How to use the Text to ASCII

  1. Paste ASCII text into the input panel.
  2. Choose the number base for the output – decimal, hex, binary or octal.
  3. Decide how non-ASCII characters should be handled: reported as an error, skipped, or allowed through as code points.
  4. Click "Convert to ASCII codes".

Frequently asked questions

Why does an accented letter cause an error by default?

Because ASCII genuinely defines only 128 characters, numbered 0 to 127. An accented letter is not an ASCII character at all, so silently emitting a number for it would misrepresent what ASCII is. The option exists if you want the code point anyway.

What is the difference between this and the Text to Decimal tool?

This tool is strict about ASCII and offers four output bases; Text to Decimal handles the full Unicode range by default and is the right choice for emoji or non-Latin scripts. For plain ASCII input the numbers are identical.

What are the codes below 32?

Control characters – carriage return, line feed, tab, escape and similar – that instruct devices rather than printing a glyph. The ASCII to Text converter can display them by name so they are visible.

  • ASCII to Text — Turn ASCII character codes back into text, with an option to name control characters such as LF and TAB instead of printing invisible bytes.
  • Text to Decimal — Convert text into decimal numbers – full Unicode code points by default, so an emoji becomes a single number such as 128512 rather than several byte fragments.
  • Unicode Code Point Converter — Look up the code point of every character – with its decimal value, UTF-8 bytes and UTF-16 units – or turn U+ notation back into text.
  • Hex to Text — Convert hexadecimal back to text, accepting spaces, commas, colons and 0x prefixes, and warning when the bytes decode to something other than clean UTF-8.
  • NATO Phonetic Alphabet Converter — Spell text out in the ICAO and NATO phonetic alphabet – Alfa, Bravo, Charlie – for reading codes aloud over phone or radio, and convert phonetic words back to text.
