I’m looking for a program or website to convert xls and xlr files to a jpeg or any other type picture format. I found one, but it only converts xls files.
One way to achieve this is to use PDFCreator which works like a printer driver. By default, you 'print' to it to create PDF files, but there are options (under 'Save=>Standard save format') to save in other formats, including JPEG etc.
The nice thing about this solution is it will work with ANY file you can print.
try Changing the extension from xlr to xls then use your mentioned soft!
