Checking if a csv cell has data or an empty string in it

this question is specific to a plugin (CSV by rexrainbow) but i assume answer may be provided by anyone who used an array in C2: Can i check if a cell in the csv actually has anything in it? - Not "Check if cell is valid" condition, but something like "Check if cell has data" - cause check if valid just gives true regardless of if cell has data in it

it can also be something like check if cell has "" in it, a.k.a an empty string, that'd do also

https://c2rexplugins.weebly.com/rex_csv.html am i missing something in these conditions?

I guess you can use something like this:

System-> compare two values -> CSV.At(row, column)=""

or

System-> compare two values -> int(CSV.At(row, column))=0

I guess you can use something like this:

System-> compare two values -> CSV.At(row, column)=""

or

System-> compare two values -> int(CSV.At(row, column))=0

you are, as always an angel of programming woes. Thank you my dude
