Hey @akalanaya, and welcome to the community.
Hope you're doing great!
When you download your data, your data will include a copy of your playlists, streaming history and searches for the past 90 days, a list of items saved in your library, the number of followers you have, the number and names of the other users and artists you follow, and your payment and subscription data. For more information, see your data rights and privacy settings.
There shouldn't be a limit of how many times you can do this, but please make sure that you don't share your personal data with anyone else.
I hope this helps! I'll be right here if you need anything else 🙂
