How to use Split a Number into Digits
- 1. Paste your number. Enter the number you want broken apart into the input pane. Works on any length of digit string, and negative signs are kept separate from the digit list.
- 2. Set the separator. Type what should join the digits in the Separator field, such as a space, comma, or hyphen. Leave it as a space if you just want 123 to read as '1 2 3'.
- 3. Copy the digit list. Copy the resulting list of individual digits from the output pane. Changing the separator instantly rejoins the same digits with the new character you chose.
When to use Split a Number into Digits
Split a Number into Digits explodes a number into its individual digits, joined by whatever separator you choose. Use it whenever you need each digit on its own instead of the number as a single value.
- Preparing input for a digit-sum function. You want to manually verify a checksum or digit-sum algorithm, like the Luhn check on a credit card number. Split the number into digits so you can add them up by hand.
- Feeding a spreadsheet formula. You need each digit of an account or reference number in its own spreadsheet cell. Split with a comma separator and paste the row directly into adjacent columns.
- Building a digit-by-digit visualization. You are laying out a number as separate boxes or tiles in a UI mockup, similar to a PIN entry screen, and need the individual digit characters listed out first.
- Debugging an off-by-one in a parsing loop. Your code iterates over a number's characters and something is misaligned. Split the number here with no separator between each digit label to confirm the exact digit order you expect.

Is Split a Number into Digits free to use?
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?

How much text can I process at once?
