Hello, when i download file as excel, if some colomn data type is number, in excel type will covert type to “None” or “str”. How to keep the original data type of the downloaded file?
I don’t think this is supported. The Excel download just takes the query result, which is a JSON string, and converts it to an Excel file. The data types are “guessed” by the front-end but the API always returns them as text. To retain the types you’d need to add type “guessing” to the Excel download code.
