Integer splitter

World's simplest integer tool

This online utility splits an integer into groups of smaller integers of a given length. You can specify the number of digits per chunk and choose from which side the splitting starts. You can also customize the output chunk format and specify the delimiter character that goes between the split pieces in the options. Created by math nerds from team Browserling.

Integer splitter tool What is a integer splitter?
With this browser-based application, you can split an integer into pieces of a smaller size. You can specify how many digits you need in one fragment and you'll get slices of this size in the output. By default, the chunkification starts from the left side and moves to the right. It's greedy and prints as many full pieces as possible from the start and leaves all incomplete pieces in the end. If you want to form groups from the end, then change the split direction to be from the right side to the left side in the options. You can also simultaneously split multiple integers into pieces at the same time. To do that, enter each value on a new line. To customize the format of the output groups, use the chunk separator option. Integerabulous!
Integer splitter examples Click to use
Integer to Three-digit Chunks
In this example, we split a large nine-digit integer into chunks of three digits. As the number 9 is divisible by 3, we get three fully filled groups, each with a length of 3 digits. Each chunk is printed on a new line because we're using the "\n" character in the chunk separator option.

Add Thousands Separator
In this example, we change the splitting direction and create groups from right to left. We set the size of pieces to three digits and configure the delimiter symbol to a comma. This way the input integers get the thousands separator added between hundreds, thousands, millions, and billions. Adding the separators between thousands allows us to quickly judge the magnitude of the integer by just glancing at it rather than counting the number of digits.

Prettify Credit Card Numbers
In this example, we enter four bank card numbers with closely spaced digits. To make it easier to read them, we split the card numbers (which are just integers) into groups of four digits in each group. The first card is from an unusual bank that has one less digit than the other cards. As we're grouping the digits from the left side, the last group of the first card is incomplete with just three digits. We put a space between the groups as it's the standard format for cards.
