type question

[soye-jy]

When uploading to the Google sheet, all data types are string.
How can I save the type?

All the changes made to the dataframe gets saved as <class type = 'string'>
Exporting this to Google Sheets results in the same datatype.
Thus you can use the values of the dataframe regarding it as 'string' datatype.

You can monkey patch the gspread lib (to not save as strings, via the USER_ENTERED option):

    def upload_pandas_df(self, df):
      values = [df.columns.values.tolist()]
      values.extend(df.values.tolist())
      sheet.values_update(
        self.title,
        params = { 'valueInputOption': 'USER_ENTERED' },
        body = { 'values': values }
      )

    gspread.Worksheet.upload_pandas_df = upload_pandas_df

Or use gspread-dataframe instead.
