What is an Integer Digit Separator?

An Integer Digit Separator is a formatting tool that makes long numbers easier to read by inserting characters (delimiters) at specific intervals. While most people use it to add commas to large currency values (like 1,000,000), it can be used for any sequence of digits. You can choose to group digits by any number (N) and start the grouping from the beginning or the end of the number. This is especially useful for formatting raw data, credit card numbers, or scientific values for reports and spreadsheets.
