what is best extension for import to database CSV,TSV, or Html

I want to import a database that can only export in CSV, TSV or HTML. What is the best procedure to import to Base? Should I first import to Calc and the Base? I am a new user. Thanks

thank you for your quick reply

Hello,

From what you present, use CSV and import into Calc. Then you can copy from Calc to Base tables.

You will find a bit more on this in the LO documentation found here → LibreOffice Base Handbook. See Chapter 3 - Tables
