We extract data from a database to a flat file, we use a pipe for column delimiter and double quotes for text delimiter.

Data file looks Something like this:

"164829" | "collection 1" | "wood plank 2" x 4" long" | "23.5" 
"2017"|"S"|"221318"|"WE"|"20170118"|"Someones name"|"20170215"|"1785"|"009"|"20170215"|"182339"|"99536"|"00090"|"LOCAL00"|"930N"|"2017"|"6100"|"0000880"|1.000|0.000|"EA"|" "|" "|" "|" "|"005"|"00000000"|" "|" "|"1785"|"50228"|"R"|"2017"|"NMT CAUTION| 5" X 3" NAT ON BLK"|" "|" "|"USD"|"7444"|" "|"000"|"COIN"|"04"|35.00|"00"

What command/script could find every case where the data (not including the text delimiter) can be escaped with a second double quote?

The end result should look like this:

"164829" | "collection 1" | "wood plank 2"" x 4"" long" | "23.5"
"2017"|"S"|"221318"|"WE"|"20170118"|"Someones name"|"20170215"|"1785"|"009"|"20170215"|"182339"|"99536"|"00090"|"LOCAL00"|"930N"|"2017"|"6100"|"0000880"|1.000|0.000|"EA"|" "|" "|" "|" "|"005"|"00000000"|" "|" "|"1785"|"50228"|"R"|"2017"|"NMT CAUTION| 5"" X 3"" NAT ON BLK"|" "|" "|"USD"|"7444"|" "|"000"|"COIN"|"04"|35.00|"00"
