I created a plugin that allows you to import definition data managed in any spreadsheet, such as Google Spreadsheets, into Roblox Studio.

This plugin supports data of any hierarchy.
Instead of importing a spreadsheet directly, it imports a CSV file.
Why CSV format?
Because it is a format that can be used in a variety of applications, such as Excel and Google Spreadsheets.
What kind of spreadsheet are you assuming?
Please take a look at the sample.
