Hi,
i have four excel work books. all the excel books are like attendance register.

First excel workbook contains name and 1 to 31 days ,each and every days considered as one column.

Second excel workbook contains name and 1 to 30 days , each and every days considered as one column.

Third excel workbook contains name and 1 to 29 days , each and every days considered as one column.

Fourth excel workbook contains name and 1 to 28 days , each and every days considered as one column.

Here File name is different for each excel workbooks.

FileName is, First-Attendance-31 , Second-Attendance-30 , Third-Attendance-29, Fourth-Attendance-28.

if FileName - Attendance-31 means, it contains the 31 columns. it like same for all excel workbooks.

Here mainly considered as the FileName.

i want January attendance details means,filename Attendance-31 excel workbook sheet import into sql server
table.

31 days months means, filename Attendance-31 is import into sql table.

30 days months means, filename Attendance-30 is import into sql table.

29 days months means, filename Attendance-29 is import into sql table, this is only for leap year for Feb month.

28 days months means, filename Attendance-28 is import into sql table, this is non leap year for Feb month.
