spreadsheet is crashing excel in Mac, but works fine in PC

M

Murph

As the subject suggests, I have a somewhat large spreadsheet - 11,000
data entries, but only about 15 columns. This data set seems to be too
much for my MAC to handle, as it struggles to put figures together and
eventually is unresponsive requiring a force quit. However, on a PC
there are no problems. The data set and all functions seem to operate
normally.

Anyone have an idea for me? I am clueless on this one.

I can assure you that the size of the record set is not the problem, but
you've provided no information that would help anyone determine what the
actual source of that problem might be. It would be quite helpful to have at
least some fundamental details, such as;

The version & update level of Excel
The version & update level of OS X
Specs for the Mac -- especially RAM
What the file format of the file is

Any additional details you can furnish -- we know nothing about your
situation other than what you tell us.

As Bob says, you haven't given us the information we need to be able to
answer this.

The latest versions of Excel will handle up to a million rows, so you're not
even scratching the surface yet.

Chances are, there are three things that will help:

1) Add memory to that Mac. Eight gigabytes is a nice round number if
you're going to get serious with Excel. Be careful where you buy it: almost
everywhere charges less than Apple will, but prices vary quite widely. Be
aware that Macs are very fussy about their memory, and may refuse to use
memory that does not match their specification exactly, so try to get it
from a shop that knows Macs well, like
http://eshop.macsales.com/shop/memory/

2) Chances are that you are using Page Layout View and have an HP printer.
Page Layout view is for making the final touches and tweaks before printing,
but it is extremely expensive on CPU time. If you want to get work done,
work in Normal View. There's a bug in the current HP Printer Drivers that
causes Excel to re-create the whole display once for each cell. That will
get the fans wailing :) Work in Normal View until HP releases new drivers.

3) Excel can save a spreadsheet in one of three file formats: .xls, .xlsx
and .xlsb. XLS will be very slow because Excel has to convert it on the way
in, and convert it again on each save. .XLSX is a plain text format that
provides full compatibility with other programs, but requires a little more
work to interpret. .XLSB is a binary format that was designed to speed
performance with large data sets. It won't be any quicker with small
spreadsheets (and other programs can't read it) but it's a lot faster with
big ones.

Now, if you come back saying you're not using the latest version, then I
have just wasted my time typing all that out, and I *will* think bad
thoughts about you!! :)

Hope this helps

Sorry for the lack of information. Here it is.

Excel 2008 for Mac, version 12.1.9
Mac OS X 10.5.8
Memory: 2GB 667 MHz DDR2 SDRAM

There is now way that I need more RAM memory to perform the simple
tasks I am doing, as i have done much more complicated things with
less RAM in the past. I would mention that I have only 14 GB on the
hard drive of about 160 GB. Is that an issue?

As I see it, Dave, you have *2* issues.

The lack of free space is definitely a concern... In order for the OS & most
any contemporary software to function properly there needs to be a minimum
of 20% free at all times (unless the HD happens to be maybe 500GB or more).

Probably of even greater significance is that your update level of Office
2008 is seriously behind. The current level is 12.2.3 & without *at least*
SP2 (12.2.0) it's surprising that you aren't having more problems than what
you've reported. Use Help> Check for Updates from any of the Office 2008
apps in order to get fully updated. Do not launch any of the Office apps
until you have not only applied all the updates but have also repaired disk
permissions & shut down the Mac for a minute or two.

It might also be a good idea once you get the AutoUpdate started to set it
to Update Automatically on a Monthly basis in order to avoid falling into
this same trap again. With the level of sophistication of today's OS &
software staying current with updates isn't optional :)

Let us know how you make out.

Hi Dave:

In addition to what Bob said, there is a memory issue there.

With only 2GB of memory, when Excel wants to open a large data set, it is
going to request the operating system to open a "Paging File" into which it
can swap bits of data as it works.

If there's no free space to create a paging file, then yes, Excel will
struggle.

I know these issues: I too have a 2GB MacBook and I too have had to delete a
heap of treasured rubbish in order to make room to work :) The machine's
too old to be worth adding memory to, so I just have to keep putting out the
garbage :)

Cheers

I have made all updates and freed about 50 GB on my hard drive and the
spreadsheet is still making the program crash... Ideas?

Chances are, during one of those crashes, Excel has corrupted that
particular spreadsheet.

I would de-corrupted by carefully re-building it, sheet by sheet.

Create a new workbook, then for each worksheet in the bad one:

* Select all of each sheet, then Copy.

* Go to the Edit>Paste Special menu and choose "Formulas and number
formatting" only.

Save it as a new file name.

Chances are, that will fix it, whatever is wrong with it. When you paste,
you may get some error messages that will reveal the source of the problem
to you.

Cheers

Hi Dave;

Have you restarted the Mac & repaired disk permissions since applying the
updates? That's always good practice even though it may very well not
correct the current problem. In order to focus on it you'll need to provide
some additional details...

Is Excel actually 'crashing' or is it 'hanging'? According to your original
post it sounds more like a hang than a crash [where the program shuts down &
produces an error report].

Is this happening with just the one file or does it happen with other files?

Can you identify any one particular action or change (such as sorting,
copy/paste, using Find & Replace, inserting a new sheet, deleting a record,
etc.) which triggers the behavior?

When you say "on a PC there are no problems", are you opening the exact same
copy of the file from the same specific HD location? Is there a network
involved? Or is that a separate copy of the file? If a different copy, what
happens if you make another copy from it & transport to the Mac?
