Woodsie,
Obi is solving (perhaps in the finest solution) your problem (partially)
He proposes isolate the wright parentheses, that means detect those that open and close: green colour.
(For this you may find regex in the web that locates them...)
Later, you may find those who are single... This regex, wrote by Obi in a forum here, may be useful:
\([^)]+\(
and you apply a colour (red, for example)...
This regex may be change, perhaps, test it:
\)[^)]+\)
But your problem is really serious. You lost information (how?) and nobody can help you to find invisible and uncertain parentheses: sometimes they thread one word, sometimes more: no way to detect them... That is ontological to resolve.
Obi proposes check the «incomplete» parentheses and with the help of yourself or another fellow reconstruct the original text.
Thank you to those that posted trying to help,
This was a dataset that I exported to word from Excel and then put in InDesign. It was an error in the excel file and not a problem with losing information in InDesign. I actually used Obi’s concept, went back to the excel file and copied the columns of information with the error twice, searched one column for a right Parentheses, highlighted them all in the view finder and applied a color to the cells. I did the same on the second column looking for a left parentheses and highlighted them another color. Sorted the first column by color, and then scanned through the data, and any with no color in the second column had the error so I could fix it there and go to InDesign, search the species name and fix it in the document. I actually use the place command in InDesign quite often to get excel files into InDesign so I can used the advanced find and replace or GREP to make modifications in the data that otherwise would be torturous to do in Excel, and then I just copy and paste the corrected data back to excel. When I have more time in the future I will try to learn more about the process described here using the regex method. Thank you all for your help!
