What Group Number Digits can do:

This tool splits digits into evenly sized groups and inserts your preferred separator. It can group digits starting from the right (like currency or phone formatting) or the left, depending on what you need.

If you paste in multiple lines of numbers, it handles each one separately. It even tracks how many were processed and shows that count below the output.

Invalid lines that aren’t digits will get flagged so you know what needs fixing.

Example:

Input:

1234567890
987654321

Output:

1,234,567,890
987,654,321

Settings: Group size: 3, Separator: “,”, Group from right: ON, Trim whitespace: ON

Common Use Cases:

This is perfect for formatting numbers in reports, invoices, datasets, or form entries. Whether it’s for readability, style, or sanity, breaking digits into chunks makes life easier and this tool makes it instant.
