How to use Convert Text to Decimal
- 1. Paste the text to encode. Paste or type the text you want converted into the input pane. Convert Text to Decimal encodes every UTF-8 byte of it as its decimal character code value.
- 2. Set the Separator. Type the character you want between each decimal value into Separator, such as a space. This keeps multi-digit codes distinct so the output can be split apart correctly.
- 3. Copy the decimal output. Click copy on the output pane and use the decimal byte values in a script, a teaching example or a low-level protocol test that expects raw character codes.
When to use Convert Text to Decimal
Convert Text to Decimal encodes each byte of a UTF-8 string as its decimal character code, the same numbers you'd see in an ASCII table. It's a direct way to turn text into the numeric values a program actually works with.
- Generating char code lists for a teaching exercise. A programming lesson on ASCII values needs example text converted into its decimal character codes so students have a reliable answer key to compare their own calculations against.
- Preparing byte values for a protocol test. Testing a low-level protocol implementation sometimes requires a known text string expressed as its raw decimal byte values, ready to feed straight into a packet-building script or test case.
- Building a char code array for a script. A script that needs to hardcode a string as an array of character codes, rather than a literal string, can get that array generated here instead of computed by hand.

About the Convert Text to Decimal tool
Convert Text to Decimal runs as plain JavaScript in your browser tab, with no server behind it. Encode text as decimal byte values (UTF-8). Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Text Tools section, 211 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with the Separator setting, and the result refreshes the moment you change it. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Does Convert Text to Decimal cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
