I started to collect these data in MS-Excel which is quite convenient for gathering big amounts of data.
I then export these data in CSV-format and import it into LiveCode.
When learning how to do this I read a lot about the csv-format being obsolet and that it should not be used if possible.
Someone in this forum compared the csv-format with polio which should be eradicated

Since I do not know much about data-formats, data tables or data grids I have no idea which data-format would be better than CSV.
Which other format is recommended for the use with LiveCode?
