6. www.OASUS.ca Additional comments November 20, 2014Tom Kari, Tom Kari Consulting6 Like PROC SORT, this procedure is intended purely for data processing PROC TRANSPOSE has no provisions for ODS PROC TRANSPOSE will frequently convert numeric variables to character Enterprise Guide provides a good Transpose task

10. www.OASUS.ca Use case 2: Edit Spreadsheets November 20, 2014Tom Kari, Tom Kari Consulting10 Spreadsheets are a terrible way to transfer important data from one organization to another: They are prone to ad-hoc changes; There’s always the risk of transferring the wrong month, version, location; “Glitches” frequently pop up. Yet everybody does it!

15. www.OASUS.ca Spaghetti code! November 20, 2014Tom Kari, Tom Kari Consulting15

16. www.OASUS.ca A different approach November 20, 2014Tom Kari, Tom Kari Consulting16 Transpose one of your spreadsheets (turn rows and columns into rows identified by cell id, e.g. B17) Separate your cells into “static” (the contents should always be the same), and “fixed” (contains data that we want to capture). Set this table up as a reference table. For your production processing: –Pull your spreadsheet into SAS (PROC IMPORT); –Transpose the cells same way, into rows with a cell id; –Match to the reference table by cell id: If static and values don’t match, we have a problem. If a reference cell is empty, and a test cell isn’t, or vice versa, do we have a problem? –Pull out your “fixed” cell ids (we know what they are from the reference table), and transpose them. You’ll get one record with your data!
