So every month I get a sheet over all purhases my company made in the form

Itemnumber:Itemname:Count:Cost

It's in the WB as a table called *month*_*year*

Where could I store them, I've got dropbox, sharepoint, onedrive, a local server - to just "drop them" down in the folder and a "master" wb would pick them up, so I could just combine them, and maybe even search "Itemnumber", to see the total!?
