CSVValueConverterFunc
A function type used to convert CSV string values to other types.
CSVValueConverterFunc is a callable that takes a string value from a CSV cell and converts it to a desired type. This allows for automatic type conversion when reading CSV data, such as converting strings to numbers, dates, or custom objects. The converter function is applied to each value in the specified column, row, or cell.
Example
var to_number = fun(str) { return to_real(str); }
var prices = doc.get_column("Price", to_number)
var cell_value = doc.get_cell("Amount", "Row1", to_number)
