Use the Read Spreadsheet File. You could then use Index Array to get the first colum and do a search for an empty string. That will give you the break between the header data and the actual data. Take all of the data after that line and convert it to a number (String to Floating/Exp Number).
Then show us what you tried. There is likely just a stupid mistake in there that you missed.
there are six column but i am able to read only first column data .
what to do for read 4 th column.
same process doesn't work.
You need to set your delimiter to be a comma. The default for the Read Spreadsheet File is a tab.
And why are you using Delete From Array? Why not Index Array?
And I noticed there is an extra comma in your data so you will get a colum of just 0s.
Here's what I was saying to do.
