ExportDevices.gs

/**
Lists Org Unit, Chrome Device Serial Number, OS Version, Last Synced User, Last Sync Date, device Status, AUE, MAC Addesses, Location, AssetID, User, Make&Model, and Notes to Sheet and sorts by OU.
So, you need to create those columns and put the mentioned headers in row 1.
Also, in the Sheet in cell N1 I put =NOW() and in N2 I put this to calculate how many days since last sync.

=ARRAYFORMULA(IF(LEN(A2:A);DATEDIF(I2:I;N1;"D");))

I then colour code column N with conditional formatting, so I can see which devices haven't been used in a long time.

Just recently I added two columns (O,P) to tell me about my ChromeOS versions.
