How to use Convert Unicode to Decimal
- 1. Paste the text you want in decimal. Paste the Unicode text you want expressed as decimal numbers. Each character's UTF-8 bytes are read in order and converted to their base-10 values.
- 2. Set a Separator between values. Set Separator to the character placed between each decimal value, such as a space or comma, so the output matches the format your script or spreadsheet expects.
- 3. Copy the decimal values. Copy the decimal values and paste them into a spreadsheet column, a lookup table, or a script that stores or compares character data numerically.
When to use Convert Unicode to Decimal
Convert Unicode to Decimal turns text into the plain base-10 byte values behind it. It suits situations where hex or binary feels unfamiliar and a straightforward decimal number is easier to read, compare, or plug into a formula.
- Building a spreadsheet lookup. You are analyzing a column of short codes in a spreadsheet and want each character's decimal value in an adjacent column to sort or filter by numeric range.
- Verifying an ASCII table entry. You half-remember that A is 65 and want to confirm it, or check the decimal value of a less common punctuation mark without opening a full ASCII reference chart.
- Feeding values into a formula. A script or spreadsheet formula needs the numeric byte value of a character to perform arithmetic, such as a simple Caesar-cipher shift, and decimal is the easiest base to work with there.
- Comparing two similar-looking characters. Two characters look identical on screen but behave differently in code, and comparing their decimal values quickly shows whether one is a lookalike homoglyph rather than the expected letter.
