Hello,

If your spreadsheets are not too big, you could use GemBox.Spreadsheet which is a free component that will make coding what you want very easy:

http://www.gemboxsoftware.com/GBSpreadsheetFree.htm[^]

The website has plenty of Samples[^].

The free version has a limit of 5 sheets/ 150 rows per sheet and can be used for any purpose including commercially.

Valery.

My spreadsheet will have approximately 1500 rows. Is there any other way than using 3rd party dll's

You will need to look at automating Office applications using your VB.NET application.

A decent tutorial:

And the obligatory MSDN link:
http://msdn.microsoft.com/en-us/library/microsoft.office.interop.excel.applicationclass(v=office.11).aspx[^]

At the bottom of the page there is example code.
