text in the row remains empty.Another improvement is that Imex=1 is used with registry value TypeGuessRows, and the TypeGuessRows value determines the data type determined by the ISAM driver from several previous data samples, which defaults to "8". You can change the number of sample rows by modifying the registry value under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft \jet\4.0\engines\excel. However, this improvement does not fundamentally solve the problem, even if we set the Imex to "1", typegues
