The Split an Integer tool takes whole numbers and breaks them into their individual digits like turning 123 into 1 2 3. It’s quick, works entirely in your browser, and supports copy, export, file import, and more. Perfect for digit analysis, learning, or formatting.

What Split an Integer can do:
This tool takes each integer you provide and splits it into space-separated digits. So 789 becomes 7 8 9, and -42 becomes -4 2 if sign preservation is turned on. You can run it on a whole list at once it handles dozens of lines with instant updates.
It’s great for digit-level analysis, breaking down values for teaching, or formatting input for puzzles, games, or forms. Everything is handled client-side no uploading, no delays.

Input:
123

Once you’ve used Split an Integer, try Separate Integer Digits to break the number into individual components more cleanly. You can also run Add Integer Digits if you want to total up the parts after splitting.
