How to use Convert UTF8 to Decimal
- 1. Paste the UTF-8 text. Type or paste the text you want converted, such as the single letter A, into the input pane.
- 2. Choose a Separator. Enter the character placed between each output number, such as a space or comma, to match the format your log, spreadsheet or script expects.
- 3. Copy the decimal values. The output pane lists each byte or code point of your text as a plain base-10 number. Copy it into a spreadsheet, a script or a debugging note.
When to use Convert UTF8 to Decimal
Convert UTF8 to Decimal turns text into the plain base-10 numbers most logs, spreadsheets and quick scripts default to when representing character codes. It skips the hex or binary notation and gives you the numbers exactly as a printf statement or a database column would show them.
- Feeding character codes into a spreadsheet formula. You are building a spreadsheet that needs the numeric ASCII or Unicode value of each character in a column for a custom validation formula. This tool generates the list quickly.
- Matching a decimal-only log format. A legacy system logs string data as arrays of decimal numbers rather than text, and you need to produce a matching reference value for a bug report.
- Writing a byte-code table for a teaching handout. You are preparing course material showing students the decimal code for each letter in a short word, without introducing hex notation before they are ready for it.

About the Convert UTF8 to Decimal tool
Convert UTF8 to Decimal runs as plain JavaScript in your browser tab, with no server behind it. Quickly convert UTF8 data to decimal numbers. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's UTF-8 Tools section, 69 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.
