About the Thousands Separator Adder
The Thousands Separator Adder helps you quickly add comma thousands separators to numbers found anywhere in a block of text — particularly useful for making financial figures, statistics, and large datasets easier to read at a glance.
Instead of manually inserting commas into every number in a report or dataset, this tool scans the whole text, finds every digit sequence, and formats it with proper thousands separators — turning "1234567" into "1,234,567" instantly, while leaving everything else in the text unchanged.
