I have this problem, I have an excel file with 20 sheets, 60 attributes, and 60 rows(file have about 1MB). And when I choose this file for import, file reading takes about 7 minutes and it is so long time, if I  need import every sheets. Can I import all of sheets in one import process or Is some way How can i speed up this process?

Thank you.

    yip, this would be possible by using the "Read Excel" operator in a loop where you use the macro "%a" for the sheet parameter. Also use %a in the data set name for writing otherwise you would override the data in each iteration. This way you could automatically import and store all sheets in one single process.
