When getting data from excelsheet to C# dataset :
I am using

C#

connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileName + ";Extended Properties=\"Excel 8.0;IMEX=1;HDR=NO;\"";

and

C#

connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileName + ";Extended Properties=\"Excel 8.0;IMEX=1;HDR=NO;\"";

I have to make general formatting for column(s), so that able to update Database as integer column.

Ex

12,220 --> 12220
15,445 --> 15445
55,881 --> 55881

Number(-1,234) --> Number(General)

I don't want fix(s) by row (by) row operation

it will degrade performance

Have you tried string.Format ?

If I am doing string.format, I have to go [row][column]
Expecting performance, Excel sheet contains around 6 Lakhs records

Formatting has nothing to do with importing data from MS Excel sheet.

Read this: Import Excel File to DataSet[^]

If you use: Provider=Microsoft.ACE.OLEDB.12.0 driver, the Extended Properties can NOT use Excel 8.0 value.

More about it, you'll find at: http://www.connectionstrings.com/excel[^] and http://www.connectionstrings.com/excel-2007[^]
Read carefuly about IMEX option ;)

But, if you got trouble with separator for thousends and decimals, try to manually change it[^] or use CultureInfo (System.Globalization)[^] class to change it programmatically (to imitate other settings).
