Sorry but I dont understand the point.

the file, named beverages.json shoult contain :

[{
“C1”: “1”,
“C2”: “Hot Chocolate”,
“C4”: “SEAVISION”,
“C6”: “01/06/1954”,
“C5”: “true”,
“C3”: “14g”
}]

as indicated before .

Using theese data, I tested it again, I see the grid with a row of  data as expected.

Tks
