I am running above program to read values from excel, query database and see all excel values are present in database or not.

If the excel values are not there in database then it will create missing list send missing list to user as the excel file.

Everything working fine as long as everything is string. But in the excel the password instead of string if I give numerical values as in attachemnt ie instead of say aaa if i give 123456789 then the program is not querying properly.

I tried following link suggestion

but did not help much but in console earlier numeric used to be read 1.23456789(something like double) but after
placing the line before reading the cell that issue fixed and reading as 123456789 itself

I went to excel column and changed all the individual cell properties which also did not help.

It is thinking all the excel values not present in database and sending email of all values. Looks like APache POI is not reading the excel numerical values properly hence not able to query database properly and hence not able to judge properly whether those values are there in database or not. So even the excel values are there in database program thinking excel values not there in database and sending missingist report with all the excel values. Please advise how can I fix this numerical issue of the Apachi poi reading issue.Any ideas, suggestions, sample code, links, source code highly appreciated. Thanks in advance

Moving discussion as too difficult for “beginning”.
