Hello Zoho Team

I have some questions/ problems to ask abut because I couldn't find a solution in the tool.

1. How can I extract all Projects with all Tasks and customized fields inside (because I need my customized fields for example formula based). Have tried with DATA ADMINISTRATION > Backup, but it just gave you the already customized fields by you. If I want to export all Tasks with my customized field, I have to go project by project and it doesn't make a sense to do for a lot of projects.

2. Last point: is there a possible way to have more number and formulas field available.

Thanks in advance for your answer
