How to Use a Text to Hex Converter with Real Examples

If you've ever needed to convert plain text into hexadecimal, a text to hex converter makes it fast and easy.

Hex codes are used in programming, data encoding, and network debugging. So knowing how to turn text into hex can save time and avoid errors.

A string to hex converter works by changing each character into its matching hex code. For example, the letter "A" becomes "41". This is based on the ASCLL system, which maps every symbol to a numeric value.

In this guide, I'll show you how to use a text to hex converter online. I'll also walk through real examples so you can see exactly how it works. Plus, I'll cover how to do the same in Python or Excel if you prefer working offline.

Let's keep it simple and practical.

What Is a text to Hex Converter?

A text to hex converter is a simple tool that changes regular text into hexadecimal code. Each letter, number, or symbol is turned into a two-digit hex value based on the ASCII table.

For example, the word "Hi" turned into "48 69". Here, "H" equals 48 and "i" equals 69 in hex.

Hexadecimal, or hex, is a base-16 number system. It uses numbers 0–9 and letters A–F. Computers often use hex because it’s shorter than binary but still easy to decode.

Most text to hex converters online show both the input and output in real time. You type text on one side and get the hex code on the other.

If you're working with data, debugging code, or just exploring how text works under the hood, a string to hex converter helps you do it fast.

How a Text to Hex Converter Works

A text to hex converter uses a simple rule: it looks up each character in the ASCII table and replaces it with its matching hex code.

Let’s break it down:

1. Each character in your text has an ASCII value.

2. That ASCII value is then converted to hexadecimal.

3. The converter returns a string of hex codes—one for each character.

Example:

• Text: A

• ASCII: 65

• Hex: 41

For the word “Cat”:

• C → 43

• a → 61

• t → 74: Final Output: 43 61 74

Some converters also let you pick a delimiter (like a space or colon) between hex values. Others let you copy the output with one click.

This is the same process behind many ascii to hex tables and hex to ascii converters.

Step-by-Step: How to Convert Text to Hex

Using a text to hex converter online is quick. Here's how to do it:

1. Enter your text: Type or paste your text into the input box. Example: Hello.

2. Choose the conversion type: Select “Text to Hexadecimal” from the dropdown. Some tools may label it as “String to Hex”.

3. Pick your delimiter (optional): You can add spaces, colons, or no separator between hex values. For example:

   • 48 65 6C 6C 6F (with space)

   • 48656C6C6F (no space)

4. Click convert or get output automatically: Some converters work in real-time. Others need a button click.

5. Copy the result: Most tools include a one-click copy button to save time.

That’s it. You’ve converted text to hex in seconds. This process also works in reverse if you use a hex to text converter.

Real Examples of Text to Hex Conversion

Let’s look at a few real examples using a text to hex converter.

Example 1: Convert “Anish”

• Text: Anish

• Hex Output: 41 6E 69 73 68 (A → 41, n → 6E, i → 69, s → 73, h → 68)

Example 2: Convert “123abc!”

• Text: 123abc!

• Hex Output: 31 32 33 61 62 63 21: (1 → 31, 2 → 32, 3 → 33, a → 61, b → 62, c → 63, ! → 21)

Example 3: Convert “@SEO2025”

• Text: @SEO2025

• Hex Output: 40 53 45 4F 32 30 32 35

You can test these yourself using any string to hex converter online. Just paste the text and see how each character turns into a clean hex code.

This helps when debugging, storing encoded data, or understanding how text is stored in memory.

Text to Hex in Excel and Python

If you don’t want to use an online tool, you can convert text to hex using Excel or Python. Here’s how:

In Excel:

You can use this formula to convert a single character to hex: =DEC2HEX(CODE(A1))

If you want to convert a full string, you’ll need to break it down by character and combine results. For small tasks, this works fine.

In Python:

Here’s a quick script to convert any text to hex:

text = "Hello"

hex_output = text.encode("utf-8").hex()

print(hex_output)

Output: 48656c6c6f

This is a clean way to create a text to hex converter in Python for larger tasks or automation.

Both methods work if you prefer offline tools. But for quick results, an online text to hex converter is easier.

Related Conversions You Might Need

Text to hex is just one part of the puzzle. You might need to switch between other formats too. Here are a few common conversions:

1. Text to Binary

Turns each character into binary code.  Example: A → 01000001

Use a text to binary converter for this task.

2. Text to Decimal

Gives you the decimal value for each character based on ASCII. Example: B → 66

Works well with a decimal to hex converter if you want to chain conversions.

3. Hex to Text

Converts hex back into readable text. Example: 41 42 43 → ABC

Use a hex to text converter or a tool that supports both directions.

4. ASCII Table

Shows each character with its binary, decimal, and hex values. Helpful when converting manually or checking values.

Look for an ascii to hex table or printable ascii table for quick reference.

These tools and conversions help when working with encoding, debugging, or system-level data.

Final Thoughts

A text to hex converter is more than just a simple tool. It helps you understand how text is stored, transferred, and processed behind the scenes.

Whether you’re coding, working with data, or just curious, knowing how to convert text to hex can come in handy. It’s fast, accurate, and works for anything from a short word to a full paragraph.

You’ve seen how to use an online string to hex converter, how to do it in Excel or Python, and even how to decode the hex back to text.

Next time you need to work with text at the byte level, you’ll know exactly where to start, and how to get it done in seconds.
