Thanks,

How I can check Excel Column cell data is string or numberic

I required only numeric data

Example
suppose
str data;
,es.GetCell(data 1 i)
'****** I required If Data is numeric value then process next step otherwise continue

I know other language
if IsNumeric(Data)
{
out "Numeric"
}
else
{
out "Character"
}

CELL VALUE IS
1234
sdsd
123
sd23

JHJHS

I required only :: 1234 123 131 for next step
