Hello dear monks, I'm back here to seek your guidance and help with regexes. Basically, I'm parsing through an excel file that has whole database of entries as a table. Now, the table has headers corresponding to every column like so : 
"Header 1"  "Header 2(%)"  "header 3 " ......

I need to read through the columns matching these keywords. The catch here is that keywords will be the same, but it may or may not include special characters, upper/lowercase characters,whitespaces in the header.

So, if my keywords are "header1", "header2", and so on,....the regex should be able to identify all possible combinations of the keyword with variations as mentioned above.
