New Post: Memory problem with ClosedXML

I was having a similar problem.
The quick version is that I was doing a loop in the loop.
My spreadsheet have about 250,000 rows.
The first pass of the 2nd loop took my 8g machine into an out of memory crash.

I solved by doing a .select to "find" the row for which I was looking.

If you want to post the most relevant code,. I will take a look at.
