i proceed to load a csv file from google sheet and display them as listview and save it in tinyDB6. However when I proceed to load a new csv file from Google sheet (new data) my listview only shows the data I have loaded previously (not the data I just loaded)
I think you should click the "Tai_du_Lieu" button again to show the data that you load.
Hmm, I think that would be great if you copy the procedure inside the "Tai_du_Lieu" button and put it to the button that you will click to upload the data to your sheet.
