How to Use the Number Separator Converter
The same number is written differently depending on the country. The US uses a comma for thousands and a period for decimals, while much of continental Europe — Germany, France, and others — does the opposite, using a period for thousands and a comma for decimals. India uses an entirely different system, the lakh/crore method, which groups only the last 3 digits together and then groups every 2 digits after that.
This converter automatically cleans up numbers even if they already contain mixed commas or periods, then instantly shows the plain unformatted number alongside US, European, space-separated, and Indian formats side by side. It's useful when adapting spreadsheet data for an international report template, or checking regional number formatting rules before publishing a document.
