Transfer Contacts to iPhone Without iTunes Follow this link

On your Sony Xperia Z phone, go to contacts list, click on the bottom right button with 3 dots icon, select 'Export contacts'. The contacts will be saved as a 'vcf' file in the location you select. The vcf file is the standard 'vCard' format used by many phones and apps. You can then import your contacts in the vcf file to your ipad.

Microsoft Outlook reads VCF files directly. Thunderbird, Windows Live Mail and other email programs will import a VCF file into the address book. For Thunderbird, if the vCard is an email attachment, just click on the vCard in the preview and add it to the address book. Double-clicking should automatically import the vCard. Any text editor (Notepad, Word) will open the VCF file with the headers visible.

However if the vcf file has multiple contact entries, you would be better off using Outlook or Live Mail to export the entries as .CSV (comma delimited text file) and then importing from that. Alternatively, edit the file with a text editor to add tabs or commas and save the file as a .CSV file. (Use the Open With command in Windows.)

There are VCF viewers available. There is one here: http://www.softpedia.com/get/Office-tools/Other-Office-Tools/VCF-Viewer.shtml . It can't edit or search the file though.

I hope this helps.

Windows phone can't do it, however you can import the vcf to a google account and then add the contacts straight from that google account
