It is now possible to import grid field data into Castor.
When a grid field is exported, each grid cell is exported as its own column, which is labeled as Variablename_rowname_columnname. This is the way the grid data should be prepared for import as well.
An example of this can be seen here. We have a grid field with the variable name 'grid_test' containing 3 rows, 'Hip', 'Knee' and 'Ankle' and 2 columns, 'Left' and 'Right'. The configuration shows that each cell contains a 'number' field.
Our spreadsheet, prepared for import, contains a column for each grid column and row:
Once prepared for import, we save the file as CSV and import into the study:
In this case numerical data is shown. If you are importing dates, make sure the date is formatted properly, i.e. in the format dd-mm-yyyy. Dropdowns should contain the respective option value.
