Let’s say PrevFile is

              PrevFile = "y"+Now.AddDays(-1).ToString("yy")+"m"+Now.AddDays(-1).ToString("MM")+"d"+Now.AddDays(-1).ToString("dd")

And then in Excel Application scope mention as below to read previous day file.

   Directory.GetFiles("FolderPath","*"+PrevFile+"*.xlsx")(0)

Create current day file name as below.

        CurrFile = "y"+Now.ToString("yy")+"m"+Now.ToString("MM")+"d"+Now.ToString("dd")

Note: Replaced mm with MM

Hi,

“mm” means minute, so we should use “MM” instead of “mm” as the following.

"y"+Now.ToString("yy")+"m"+Now.ToString("MM")+"d"+Now.ToString("dd")
