How to Check if the order of columns in two files is same?

I have two files containing columns names ,I need to validate if the columns are in the same order.

 

For eg : File1

ID;Name;Address

File2

ID:Address:Name

 

If these are the input files.I should be able to extract the columns which are in the wrong order.

If you don't need to identify all the differences but just check if both header lines are identical, I suggest you to extract them and concatenate the values into a single string for each file giving something like "field1;field2;field3" for the 1rst file and maybe something like "field1;field3;field2" for the 2nd file. Then you can compare the strings.

Use tFileInputFullRow with Limit=1 to get header line from yours input files.

Then use String.equals() or String.equalsIgnoreCase() methods to compare both header lines.

If they don't match, order is not the same or column names are different.

No, this is for simple text files.
For Excel files, if you have a header line, you must do it by yourself.
