Subject: Re: [libreoffice-users] Problem loading and saving XLS files
Thanks, Tom. I'm on a Mac so those memory settings are under
LibreOffice->Preferences->Memory.
I set per object memory to 18MB and then 20MB based on the 15MB file
size and left the others. I don't care if it's slow for testing
purposes. I run 4GB ram and typically have over 1GB available, so no
problem there...at least in theory.
Changing the memory didn't affect the file opening. Still truncating at
7,600+ records. Note there are no images in the files. They are
straight text and numeric data with up to 25,000 records and 17
fields/columns. The only formatting is that the first row is
boldface. When I save the .csv file (the one that contains all records)
as a .xls, the files size is 3-4MB, much more like what I expect.
I will certainly inquire with Salesforce to see what they do for file
generation, though I don't expect much of a response.
Re: gnumeric, I don't see a build for Mac OS and I always have LOTS of
trouble building from source code. I may try it eventually, though, so
thanks. It certainly sounds interesting.

Hi :)
I'm just wondering if Gnumeric might be better at opening the file?
Calc 'should' be able to handle it easily so there is something weird there. The file-size drop
sounds like the old bug about images dropping out but we haven't seen that happen for around a
year afaik. Is it definitely an Xls and not an XlsX? XlsX and Odt can be opened as though they
were Zip files which allows you to poke around inside a lot more. On the other hand Xls is
usually a lot more stable than XlsX. 15Mb is pretty large for a normal file unless it does have
images embedded inside.
Could you just open LibreOffice itself, without opening the Xls, and go to
Tools - Options - Memory
and bump up those figures a LOT. Particularly the "Memory per object" to maybe around 15Mb, or
something huge like that. I'm assuming your Ram is over 1Gb and could handle it quite easily.
Perhaps drop the number of undo steps it remembers to maybe 50. Mine seems excessive at 100.
I don't know why the file-size keeps changing. It's something that would worry me so i would
save as an Odt to make sure i got a stable copy and then possibly start exploring the Xls to see
why it's so unstable. Csv holds no formatting information so it's bound to be a lot smaller
than an Xls or Odt. It also strips out any images and macros and stuff.

Tom :)

I'm using LO 3.5.6.2 on a Mac OS 10.6.8
I'm working on a critical project analyzing data from Salesforce (I'll call it SF) for
non-profit SF users. When I export xls files from SF, if those files are greater than
something like 7,000 records (a dozen or so fields), the file gets truncated by LO. The files
(some with 21,000+ records) open fine in MS Excel (on a PC at least - I don't own Excel on my
Mac).
If I export from SF as .csv files, these open fine in LO and I can manipulate them fine.
Saving is also OK and I seem to be able to export to .xls, which then opens fine in LO with
all 21000 records.
Any idea why the SF export of .xls file type won't open properly in LO? What could cause this
problem? Could this be a bug in LO? I realize there could be oddities in the SF export
function, but given it opens fine in Excel (on a PC at least)
Note I can see something going on with the file size. The .xls direct from SF is 15MB. After
opening this file and then saving it, the file size is 3-6MB (and it has only about 7000
records). The .csv file that's exported from SF is about 2-3MB, but when I save the .csv file
as .xls, the file is still only 3-4MB but it's complete (all 21000 records).

The problem is not the number of records since importing the csv file does not truncate. Most
spreadsheets do have an upper limit for the number of records and for Excel and Calc I believe
it is much larger than 21K.
Can you import the csv file and then save as an xls file and then reopen the xls file without
data loss?
