    declare @ImportPath NVARCHAR(MAX)='G:\ImportExportExcel'
     declare @DBConnectionString NVARCHAR(MAX) = 'dsn=Testserver;Uid=sa;Pwd=321'
     declare @ImportAll BIT=0
     declare @CombineTarget BIT=0
     declare @ExcelFileName NVARCHAR(200)='dbo.studentsdata'
     declare @ExcelSheetName NVARCHAR(50)='students2'

    SELECT @ImportPath = CASE WHEN RIGHT(@ImportPath,1) = '' THEN @ImportPath ELSE CONCAT(@ImportPath,'') END

    DECLARE @ValidPath TABLE (ValidPathCheck BIT)

    INSERT @ValidPath
    EXEC sp_execute_external_script
    @language =N'Python',
    import pandas as pd
    d = os.path.isdir(ImportFilePath)
    OutputDataSet = pd.DataFrame([d],columns=["Filename"])'
    ,@params = N'@ImportFilePath NVARCHAR(MAX)'
    ,@ImportFilePath = @ImportPath

    import pandas as pd
    import os

    from revoscalepy import RxSqlServerData, rx_data_step
    sqlConnString = "Driver=Testserver;Server=Serv; ',@DBConnectionString,'"
    Filefolderepath = ImportFilePath+"*.xlsx"

    if ImportAll ==0:
    Filename =ImportFilePath+ExcelFileName+".xlsx"
    exists = os.path.isfile(Filename)
    if exists and ExcelSheetName in pd.ExcelFile(Filename).sheet_names:
    Output = pd.read_excel(Filename, sheetname=ExcelSheetName, na_filter=False).astype(str)
    if not Output.empty:
    sqlDS = RxSqlServerData(connection_string = sqlConnString,table = "".join(fl for fl in ExcelFileName if fl.isalnum())+"_"+"".join(sh for sh in ExcelSheetName if sh.isalnum()))
    rx_data_step(input_data = Output, output_file = sqlDS,overwrite = True)

    I add odbc connection to my pc and test it success

    Test success connection
