ASCII Converter

Convert text to ASCII codes or turn ASCII codes back into readable text with TextNivo’s free ASCII Converter. The tool supports conversion in both directions, allowing you to quickly check character codes or decode space-separated decimal codes.

Enter or paste your content, select the conversion direction, and view the result instantly. You can then copy, download, or print the converted output.

How to Convert Text to ASCII

Select Text → ASCII codes and enter the text you want to convert. The ASCII Converter displays the decimal character code for each character.

For example:

ABC

converts to:

65 66 67

In this example, uppercase A has the decimal ASCII value 65, B is 66, and C is 67.

How to Convert ASCII Codes to Text

The converter also works in reverse. Select ASCII codes → Text and enter space-separated decimal character codes.

For example:

65 66 67

converts back to:

ABC

This provides a quick way to decode decimal character codes without looking up each value manually.

Text to ASCII and ASCII to Text in One Tool

TextNivo combines both conversion directions in one ASCII Converter. You can switch between converting readable text into decimal character codes and decoding those codes back into text.

This is useful when checking character values, learning how text is represented numerically, decoding a sequence of character codes, or working with text-based data.

What Is ASCII?

ASCII stands for American Standard Code for Information Interchange. It assigns numeric values to letters, digits, punctuation marks, control characters, and other characters in its standard character set.

For example:

A = 65
B = 66
a = 97
0 = 48

These decimal values allow characters to be represented numerically.

ASCII Code Converter for Letters and Text

You can use the tool to convert individual letters, words, sentences, and other text into decimal character codes.

For example, entering:

Hello

produces a sequence of decimal codes representing the characters in the word.

You can also paste supported space-separated decimal codes into the reverse mode to turn them back into readable characters.

How to Use the ASCII Converter

1. Choose Text → ASCII codes or ASCII codes → Text.
2. Enter or paste your text or decimal codes.
3. View the converted result.
4. Use Copy result to copy the output.
5. You can also download the result as a text file or print it.

When converting codes back into text, use the space-separated decimal format expected by the converter.
