It was easy to fill out but I had trouble finding information on 'other' in the first section. I didn't quite understand exactly if I was to put "nonprofit organization" on the line.

I have used the free trial twice. When I signed up for a $6 one month personal subscription I was billed $20USD. I have sent an email about this and hope to have it resolved.

How do you condense the size of an Excel file?
Reduce the number of worksheets If you have worksheets with data that you're not using—and that don't contain any formulas you're using—delete them from the spreadsheet. The more data points you have in your workbook, the larger your file size will be. Removing unused data will reduce your file size.
How do I reduce the size of an Excel file without deleting data?
Compress the File (ZIP IT) Right-click on the Excel File. Hover your cursor on the Send to option. Click on the 'Compressed (zipped) folder' option.
How do I split a large Excel file into multiple smaller files?
Split a workbook to separate Excel Files with Move or Copy feature Select the sheets in the Sheet tab bar, right click, and select Move or Copy from the context menu. In the Move or Copy dialog, select (new book) from the To book drop down list, check the Create a copy option, and click the OK button.
How do I shrink an Excel spreadsheet to fit?
Shrink a worksheet to fit on one page Click Page Layout. Select the Page tab in the Page Setup dialog box. Select Fit to under Scaling. To fit your document to print on one page, choose 1 page(s) wide by 1 tall in the Fit to boxes. Press OK at the bottom of the Page Setup dialog box.
