SUMMARY
Sometimes it takes a considerable amount of time to close one or more
sheets, or exit completely from Microsoft Excel. Usually this is caused by
an inefficient design of one or more sheets, or certain interactions
between sheets (that is, macro sheets, worksheets, and even charts).
Following some basic rules may greatly improve this somewhat rare, sluggish
behavior.
MORE INFORMATION
Listed below are some of the reasons why it may take very long to either
close a sheet or exit from Microsoft Excel:
- Calculation is slow.
Possible Solutions
------------------
a. From the Options menu, choose Calculation.
b. Select Manual and uncheck Recalculate Before Save.
c. If your spreadsheet contains data tables, select Automatic
Except Tables as your calculation mode.
d. Optimize worksheet organization or redesign your model. (See
the pages referenced below.)
- A Large number of links are used.
If a source (supporting) sheet is closed, all the formulas that
contain links in the dependent sheet need to be updated. The more
links there are, the longer this takes.
Example
-------
Sometimes it seems practical to use a large number of VLOOKUP
functions to create the effect of dynamic data extraction. Often
this constitutes very large arrays, conserving memory, but not
reducing calculation time. When closing the independent (source)
document first, all VLOOKUP functions need to be modified to
include the path of the source data. After the independent sheet is
closed, the dependent sheet may then first recalculate before it
closes too. This process can take up to 10 minutes, or even half an
hour.
Possible Solutions
------------------
a. Close the dependent sheet first.
b. From the Options menu, choose Calculation and cancel the
selection of Save External Link Values.
c. Reduce the number of external links.
