ASCII to Text Converter – Decode ASCII Codes Instantly
Need to convert ASCII codes back into plain text? Our online ASCII to Text Converter makes it easy—just paste your codes and get readable output in seconds.
What Is an ASCII to Text Converter?
An ASCII to Text Converter is a web-based tool that decodes sequences of ASCII codes—numeric values representing characters—back into legible text. ASCII (American Standard Code for Information Interchange) assigns each character (letters, digits, punctuation, control codes) a number from 0 to 127. Whether your data stream uses decimal (e.g., “72 101 108 108 111”) or hexadecimal notation (e.g., “0x48 0x65 0x6C 0x6C 0x6F”), an Ascii to text converter online automatically parses those values, looks them up in the ASCII table, and yields the corresponding characters. This eliminates manual lookup and transcription errors, saving you time and ensuring accuracy.
Example (Decimal Input):
83 111 109 101 32 65 83 67 73 73 32 99 111 100 101 115 → Some ASCII codes
Example (Hex Input):
0x53 0x6F 0x6D 0x65 0x20 0x41 0x53 0x43 0x49 0x49 0x20 0x63 0x6F 0x64 0x65 0x73 → Some ASCII codes
Why ASCII Still Matters Today
Although Unicode has largely supplanted ASCII for global text encoding, ASCII remains foundational. Many network protocols, legacy systems, IoT devices, and programming languages still rely on ASCII or a superset of it. When you capture raw data from sensors, routers, logs, or APIs, you often get ASCII code dumps. A reliable convert ASCII to text tool helps you:
- Interpret log files with embedded ASCII values
- Recover text from corrupted or binary-encoded files
- Prototype IoT messages in constrained environments
- Learn programming by exploring how characters map to numbers
ASCII Code Table: Quick Reference
Decimal | Hex | Character |
---|---|---|
65 | 0x41 | A |
66 | 0x42 | B |
67 | 0x43 | C |
97 | 0x61 | a |
98 | 0x62 | b |
99 | 0x63 | c |
48 | 0x30 | 0 |
49 | 0x31 | 1 |
50 | 0x32 | 2 |
How to Use ConverTXT’s ASCII to Text Converter
- Paste your ASCII codes (decimal, hex, or mixed) into the input area above.
- Select “Decimal” or “Hex” mode if prompted, or let the tool auto-detect the format.
- Click the Convert button—your codes instantly map to readable text.
- Review the output for any special characters and click Copy Result.
Supporting Both Decimal & Hex Formats
Our converter recognizes:
- Decimal ASCII: Plain numbers separated by spaces or commas.
- Hex ASCII: Prefixed with “0x” or written as two-digit hex pairs.
- Mixed Input: Combine decimal and hex in one string—the tool handles both seamlessly.
Common Pitfalls & How to Avoid Them
When manually decoding, people often run into:
- Missing separators: “656667” is ambiguous; always separate codes by space or comma.
- Wrong base: Treating hex as decimal yields gibberish (“0x41” vs “41”).
- Control codes: Values below 32 represent non-printable controls—use “Show Controls” mode if you need to see tab or newline markers.
- Extended ASCII: Codes 128–255 belong to various code pages; our converter focuses on standard 0–127 ASCII.
Advanced Use Cases for Developers
Software engineers and DevOps professionals use an ASCII to Text Converter to:
- Debug network traffic containing ASCII payloads

Hex to Text | Raw hex strings | Memory dumps, packet inspection |
Unicode to Text | Unicode code points (U+xxxx) | International text processing |
Frequently Asked Questions
Can I convert mixed ASCII formats?
Yes—our converter auto-detects decimal and hex in the same input and decodes both seamlessly.
Does it support extended ASCII (128–255)?
This tool focuses on standard ASCII (0–127). For extended character sets, use our Unicode to Text Converter.
How do I decode control characters?
Control codes (e.g., 10 for LF, 9 for TAB) display as “\n” or “\t” markers. Enable “Show Controls” mode to see them explicitly.
Is there a limit to how much I can decode?
You can process as many codes as your browser can handle—typically tens of thousands at once.
Is this tool free and secure?
Yes. Conversions run entirely client-side; we never log or store your data.
