Very easy, indeed !

So, the general form to catch any text, without leading blank characters, located in the column N, is, simply :

SEARCH : (?-s)^(.*?,){N-1}\h*\K[^,\r\n]+

IMPORTANT :

• Of course, you need to select the Regular expression search mode

• In the regex, replace the generic form N-1 by a REAL number. For instance, if you would like to reach the 13th column, you’ll replace the form N- 1 with the number 12 ! So, in your case, you need to type the regex (?-s)^(.*?,){2}\h*\K[^,\r\n]+, in order to catch the number 2000 of the third column !

Notes :

• To begin, the (?-s) modifier, ensure that the dot symbol matches standard characters, only, even if you previously checked the . matches newline option !

• Then, the zero-length assertion ^ represents the very beginning of any line

• The syntax (.*?,){N-1} represents any text, after the beginning of a line, without commas, till an ending comma, repeated N-1 times

• The \h* stands for possible horizontal blank characters : Space ( \x20 ), Tabulation (\t) or No-Break space ( \xa0 ), leading the column N

• The \K form reset the regex engine, so that everything previously matched is forgotten. So the regex engine position is, now, located just before the first non-blank character of column N

• Finally, the [^,\r\n]+ is a negative class of characters which stands for any non null range of characters, different from a comma and from the EOL characters \r or \n

=> Therefore the final match, on each line, is, only the whole text of column N, without possible leading blank characters and without the ending comma or without the EOL characters, if column 16 is chosen !

Et voilà !
