awk code not executing on windows powershell

[hariPurohit]

I installed awk & gawk via their website and added the awk path in my PATH environment variable. When i try to run the code: awk -vFPAT='([^ ]*)|("[^"]+")' -f convert_pgn_to_json.awk game.pgn for the game.pgn file via Windows PowerShell terminal, no output is generated on the terminal except a generic awk info and no output .json file is also generated.

If i remove -vFPAT='([^ ]*)|("[^"]+")' from the code above, there's in-terminal output of the game moves and other info in a textual json like format. If i save that by doing this: awk -f convert_pgn_to_json.awk game.pgn > game.json then a file is generated but the output is not in a json like tree format as seen in your already existing game.json file.

What can be done in this case?
