I have a spreadsheet for contact information with hyperlinks to 'click to call' and 'click to email'. The file will be emailed to another person for use on their iphone. They do not want to add this list to their telephone contacts. The links work on my desktop windows10, excel 2013. After emailing to the user, the email links work, but the telephone links do not. Any ideas on what might be the problem? How do I fix this? Would it help to save the excel file as .ods format? I have tried both tel:555-555-555 with the tel: appearing in the data, and with the tel: hidden in the hyperlink. This is the format of the numbers in the file. Thanks for your help
