Excel Xlsb size Issue

Aspose.Cells Product Family
1

Hi,


I’m trying to use the Excel format XLSB to my project.
Aspose do the work well done, I mean, save the file.

The issue is that, the saved file grows a lot.

In attach we’ll find a small Console Application project so you can see what I’m talking about.
In the test I inserted a file with 314Kb which, after save and with none changes, grows to +/- 850kb.

When I open the saved file with Excel 2010, and the save (nothing more), the file decreases to +/- 314kb.

Of course that the problem is when we talk about big files (10 Mb, or more), which is the case.

I already tried to use the XLSB Save options, but with no success

var saveOptions = new XlsbSaveOptions();
saveOptions.ClearData = true;
saveOptions.ValidateMergedAreas = false;
saveOptions.SaveFormat = SaveFormat.Xlsb;

Can you please help?


Thanks in advance

Hi,


Thanks for this.
This is a big issue for us, not only because the size of the file, but also because it takes to long to open those files in Excel.

My thoughts would be something about “compact” the file content?!..

thanks,
Ricardo

Hi,

Thanks for your posting and using Aspose.Cells for .NET.

Please also try setting the XlsbSaveOptions.ValidateMergedAreas as true, it will remove invalid
records in your files which should compact the file size and also it will open in Ms-Excel quickly.

Let us know if the above setting works fine.

We have also logged your provided information in our database for investigation. Once there is some update for you, we will let you know asap.

Hi,


I’ve try what you said, but the problem still the same.

Another thing, that I already mentioned before, is the time that Excel spent to open those worbook after Aspose Save…

(+/-) Times, and size, to open workbook in excel (try the file that I’ve sent to you)…
File saved by aspose:
size: 860kb
time to open: 15 seconds

After open in Excel, just save the file (no changes)
Size: 318 kb
time to open. less than 1 second
thanks in advance,
Ricardo

Hi,

After some testing (complexity of project development) I realize that this issue is not yet finish.

If the original excel file has some pick list values, when I do the save with aspose, then those pick list values "vanish".
I've done a sample project so you can check it.

1) in the project that I attach, open the "\xlsbTemplates\Testing.xlsb"
there you can check the pick list working

2) run the project and find the file that I create (with aspose) in "d:\nochanges.xlsb" (if you don't have a drive d:\ please change the destiny of the file)

3) open the created file ("d:\nochanches.xlsb") and you can check that the pick list values has vanish.

If this issue should be in a new thread, please let me know.

Thanks in advance,
Ricardo
