Hex to ASCII Converter

This tool converts hexadecimal byte values into their corresponding ASCII characters. It is useful when you need to read hex-encoded data from logs, network packets, memory dumps, or protocol traces.

The conversion runs locally in your browser. You can enter hex values separated by spaces (e.g. 48 65 6C 6C 6F) or as a continuous string (e.g. 48656C6C6F).

How to use

  1. Enter hexadecimal byte values in the input editor. You can use spaces between bytes or write them as a continuous string.
  2. Click Convert to decode the hex values to ASCII text.
  3. The ASCII result appears in the output editor.
  4. Use Copy for the clipboard, Download for a text file, or Clear to reset.

Input format

Each byte is represented by two hex digits (0–9, A–F). The tool accepts both uppercase and lowercase hex letters. Bytes can be separated by spaces, commas, colons, or dashes, or written as one continuous string.

Example

--- Hex Input ---
48 65 6C 6C 6F 2C 20 57 6F 72 6C 64 21

--- ASCII Output ---
Hello, World!

MCP integration

MCP (Model Context Protocol) lets AI agents and apps discover and run Coding.Tools utilities for repeatable conversions, formatting, hashing, and generation workflows.

MCP tool name: hex-to-ascii

MCP endpoint: https://coding.tools/mcp

Call tools/list first. Each tool entry includes inputSchema, outputSchema, and examples so an AI agent or client can build valid arguments without guessing.

For tools/call, read result.content[0].text for the display value and result.structuredContent for machine parsing. Tool-level failures return isError: true; protocol failures return a JSON-RPC error.

Example tools/call request:

curl -s https://coding.tools/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -H "MCP-Protocol-Version: 2025-06-18" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"hex-to-ascii","arguments":{"input":"53 74 61 74 75 73 3A 20 4F 4B"}}}'

Most text and data tools accept an input string plus optional options. Browser-only image tools are listed for discovery and return a web UI link when they need browser image APIs.
