I have an inventory of over 3000 items, each item has its own spreadsheet listing name, year, company, etc. In each spreadsheet there is also an AVG function for price fluctuation, with a defined array of up to 500 entries and a COUNT function of entries to average. I was looking for a way to create a master spreadsheet compiling all item spreadsheets without having to either copy/paste data from each separate spreadsheet to the master (static data) or linking each cell from over 3000 spreadsheets one by one.
I came across @Lupp 's brilliant solution here (How can I combine the data from ~2000 calc files into a single csv file? ) and set about adapting the example to my needs.
Unfortunately, once I get over 250 or so entries, LibreOffice starts to bog down, CPU- and RAM-wise. Over 1000 entries and LibreOffice uses 4.7GB of RAM and 100% CPU, taking well over a minute to register changes and/or saving the document. Even scrolling stalls the program. For the technically curious, I’m on an i3 laptop with 6GB RAM running Ubuntu 16.04 LTS, LibreOffice 5.1.6.2. Yes, it’s not the latest machine out there but more than sufficient for office-suite work. I can’t imagine that the original poster @henryh13 didn’t experience the same kind of performance issues.
Can @Lupp or any of the other resident experts here think of a less-CPU/memory-intensive way of corraling thousands of .ods files in a master document? Thanks in advance.
