Quick Tip

If your text looks like gibberish or has characters, try switching the charset to ISO-8859-1 or Windows-1252.

Decimal to Text Decoder

The Convert Decimal to Text tool is your translator for the numeric language of computers. It takes a stream of decimal numbers (like 72 105 33) and reconstructs the original text message (Hi!). It supports everything from standard ASCII to complex UTF-8 byte sequences.

Common Uses

Data Recovery

Decode data logs or network packets that are stored as decimal byte arrays.

Education

Learn how computers store text by manually decoding ASCII values.

How it works

  1. Input Parsing:

    We scan your text for numbers, ignoring separators like spaces, commas, or brackets.

  2. Byte Construction:

    We create a byte array (`Uint8Array`) from your numbers.

  3. Decoding:

    The bytes are decoded using UTF-8 standards to reconstruct the final string.

Frequently Asked Questions

What is the Convert Decimal to Text tool?

This tool translates a sequence of decimal numbers (like 72 101 108 108 111) back into human-readable text (Hello). It is the reverse of our Text to Decimal converter.

How do I use this decoder?

Paste your space-separated numbers into the input box. The tool automatically detects the numbers and reveals the text instantly.

What formats does it accept?

We are very flexible. You can separate numbers with spaces, commas, newlines, or even brackets (e.g., [65, 66]). We filter out non-digits.

Can it decode emojis?

Yes! If you input the correct UTF-8 byte sequence (e.g., 240 159 152 138), it will be decoded into an emoji (😊).

What is ASCII?

ASCII is a legacy encoding standard where numbers 0-127 represent English letters and control characters. 'A' is 65, 'a' is 97.

Does it support extended ASCII?

Yes, it supports values up to 255 (extended ASCII) and multi-byte UTF-8 sequences for full Unicode support.

Can I upload a file?

Yes. Click the Upload icon to load a text file containing decimal numbers. This is great for analyzing raw data dumps.

How do I save the output?

Click the Download icon to save the decoded text as a .txt file, or use the Copy button to copy it to your clipboard.

Why do I see squares or weird symbols?

This usually means the Input numbers are not valid ASCII printable characters (like control codes 0-31) or incomplete UTF-8 byte sequences.

Is this tool free?

Yes, completely free and unlimited. No sign-up required.

Is my data sent to a server?

No. All decoding happens locally in your browser using JavaScript. Your data remains private and secure.

What is the maximum number value?

Since we treat the input as a byte stream for maximum compatibility, individual numbers should ideally be between 0 and 255.

How to decode hexadecimal?

Please use our specific 'Convert Hex to Text' tool for hexadecimal strings like '48 65 6C 6C 6F'.

Can I decode binary?

For binary strings (01001000), please switch to our 'Convert Binary to Text' tool.

Why is 'A' 65?

This assignment comes from the original ASCII standard developed in the 1960s, based on telegraph codes.
