Hey there, welcome to the Community!
It sounds like you want to export your boards as CSVs so you can open them in Excel, is this correct? If so, this feature is available natively in Trello for our Premium and Enterprise plans. You can check out the features and pricing for Premium over at https://trello.com/pricing
There are a few third-party Power-Ups that also offer the ability to export boards as CSV files, you can find these over at https://trello.com/power-ups/search?q=export
