A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I go to http://www.google.com/transliterate
Choose Hindi in the dropdown then (Arabic is also an option)
Type my numbers and then paste them back in Excel/Powerpoint
sample..
१२३४५६७८९० Hinid
١٢٣٤٥٦٧٨٩٠ Arabic
btw I do NOT need any special fonts... the above sample is using Calibri. It works with Arial etc. too.
The format, in Excel, of the cells I paste the Hindi numerals changes to
Custom->[$-4000439]0
For Arabic it is
[$-2000401]0
If I have this format in any cell, in Excel, then I can directly type in Roman numbers to get Hindi numbers.
