I'm using Excel 2010 with Win 7 64 Pro. I have a few big spreadsheet (for me) in an XLSM file, which I use to count occurrences of texts pattern. The text is usually imported form a text file (plain text) created from a PDF file. I'm using "COUNTIF" and "INDIRECT" within it. It was all working fine up to today.
As it happens, the formulas are not working anymore. I've tried everything obvious: automatic calculation on/off, calculate now, put text as "general" instead of "text", and even replacing "=" by "=". Nothing is working. Well, strangely, I managed to have the formulas work on one column (out of 7) on one spreadsheet (out of 4). I don't see any difference between the one working and the one not working. The only thing I could link to the one working is that I did some panic copy/paste and suddenly the formulas on the column worked (can't remember what I did, but it seemed that I pasted outside the usual place where the PDF/text import used to be, and then move it back; not 100% sure though). Maybe something has changed with the way Adobe exports to plain text (I seem to have lost the table format, so I had to use different methods to get the text imported into Excel). However, plain text is plain text, why would this cause a problem?
Another change I've noticed is that, a few days ago, I installed some Office updates (through Windows update), as they were advised (security problem). Could that be the problem? I did reboot after installation but not since the Excel problem appeared. The
updates were KB2760410 to KB2598242 (~30 installed, not all for security). Should I uninstall all?
Can anyone help? I'm desperate at this stage.
