[Solved] To Add extra commas to a CSV file.

Hi All,

I got this requirement to process a complex CSV file.

Eg File.
Code:
Line 1: Name:,XYz
Line 2: Age:,15
Line 3: Grade:,7
Line 4: 
Line 5: English, Maths, Science,Spanish
Line 6:10,11,13,14

As you can see the maximum column is 4 . The file i need to make is
Code:
Line 1: Name:,XYz,,
Line 2: Age:,15,,
Line 3: Grade:,7,,
Line 4: ,,,,
Line 5: English, Maths, Science,Spanish
Line 6:10,11,13,14

Please notice the extra commas for those lines which is less than 4 ...

This has to be performed in Unix... I have to find out the maximum column length and apply the commas for those lines which does not have them.

Thanks in Advance.
