Importing excel worksheet among multiple worksheets

Hi,

I am having a doubt:

Suppose I have an excel which have 4-5 tabs (Worksheet) with data in it, but I want to import only 1 sheet. Then when I upload the data in query editor I see the other workbooks name as well in the bottom right corner (while processing in query editor). Is power BI spent some time in looking into other worksheet too which are the part of the file (but not needed for our report).

I think it makes my data load slow.

If it does then any idea to avoid this and make the process faster

Any opinion, Thanks.
