Question

I need to access an excel file, but the application needs to run on a server with no Office installation – so interop is out of the question.

I know there is OleDbConnection, which will work, but is having strange effect when reading in Header rows. When looking at headers, it will replace “.” with “&” because it is treating the header as a database column name, and “.” is unacceptable. So, I tried to read the headers in as data, but this caused certain columns to be null – particularly when using dates.

Anyway – looking for a way to read in Excel cell values without using these two methods?

P.S. Also trying to avoid 3rd party libraries – unless they’re lightweight and free…

Answer 1

you dont mention what you actually need it for, if you are querying there are some LINQ to Excel solutions

Linqtoexcel

just noticed you 3rd part restriction however the above may still be suitable
