I am trying to take a value in a CSV file and then search the rest of the file for that value and replace it with another value. This is a small portion of the file (see attached); so on line one you have these values
"061", "Blaze", "blaze.jpg","015, 019, postman-joyner.jpg" & "aaron.jpg gingerland.jpg candidum-jr.jpg"
I want to take the 3rd value (blaze.jpg) and then look for blaze.jpg in 4th and 5th columns and in all the rows of those two values/columns and replace it with "061" -- the first value in the row. The goal is to end up with no names in values 4 or 5 (or columns 4 & 5) and have them replaced by values from the first value. So wherever the name blaze.jpg shows up in the rest of the file, have it replaced by the corresponding value in value/column 1 -- hope that makes sense. I did a few of them manually so you can see what happens in columns 4 & 5. Related-Product.csv
