I get a data dump evey night from an outside source that I have little to no control over. They tell me that they are exporting the excel files as 2003. But when I try and open it in excel 2013 I get the attached error. I've tried everything I can think of and the only way I can get it to open without issue and subsequently get imported into a SQL table is to manually open the file , save it as 2003, and then manually import it into SQL. I'm looking to automate this process at 2am in the morning. Is there somewhere a log file exists that tells me what it "thinks" it is?
