Deb has a client with 320 sites in their account for which they want to import and configure users. The user import spreadsheet creates a column for each site in the account. XLS files support a maximum of 250 columns, which causes the client to encounter an error when attempting to download the import sheet because it can't be built. XLSX files support thousands of columns and should correct this problem.
