Efficiency - Multiple Excel Files vs One file multiple sheets / tabs

[Anonymous]

Hi

Using Excel files in Sharepoint, is it more efficient to import from multiple Excel files or from one file with multiple tabs? Or is there no practical difference?  I'm talking about 12-15 tables. 

I have no current issues, but I want to avoid possible future problems, and I just prefer to use the more efficient method if one exists.

TIA

Hi Xiaoxin Sheng

thanks for the reply, that sounds like good advice. I had wondered if there was a hit in terms of time to load for using multiple files, or a bottleneck for using multiple sheets in one file, but I guess it's not significant - I haven't seen any noticeable problems with either method. So I'd agree that from a development and maintenance point of view using one file is a more practical solution.

Thanks again for your help

HI @Anonymous,

I think get data from one file should be better, you only need to get data from one source file, then you can duplicate the query table and change the navigate steps to redirect to different sheets.

It also helps you to reduce maintain time and you only need to handle one data source file.
