Hi David,

What happens when you run this code?

only Console opens(command prompt)

Does the Excel window appear?

No

Do you receive an error?

No message appears

Do you have Excel installed on that PC?

Ms Excel is installed

Does the workbook already exist? Or are you looking to create a new
workbook?

already exists

Problem - unable to open Excel with this code.
Want to open (visible) and want to write text and then save.

Thanks
Riya

You’ll need to provide more details.

Riya,

Not sure if this is the problem but your code is:

excel = WIN32OLE.new(“excel.application”)

On David’s site, the line is:

excel = WIN32OLE::new(‘excel.Application’)

Notice the capital A in Application; however, in irb on my PC, it works
irrespective of the case. So, that’s probably not the problem. What
version of Excel is installed on the PC on which you are running the
code? Do you get any other errors at all?

Could you try going line by line in irb to see if it dies anywhere?

Cheers,
Mohit.

Thanks every one

Now the below code is working

'To open Excel file
require ‘win32ole’

xl = WIN32OLE.new(‘Excel.Application’)

xl.Visible = 1

wb = xl.Workbooks.Open(‘c:\file.xls’)

Thanks again to all
