I want to read Excel file . how to do it in simple way.
View 2 Repliesi'm trying to read an excel file and get data on a row by row basis. Since after converting the pdf file into an excel file, the formatting went a bit haywire but if read row by row, i'm still able to retrieve the original data.
As I am unable to generate the excel file using a single worksheet, i have multiple sheets in the excel file. I also need help on reading multiple sheets.

I am creating an site where a user uploads an excel file to check if any of the records exist in a database. Then they are returned an excel file with only the records that are NOT in the database.
I was thinking I should do it this way1. User uploads their excel file. The app opens excel file and loads records into a dataset (so far this is working with the code below)2. Using datarow and another function to check if each excel record exists in the database3 If the record does NOT exist, and it is the first record tested, create an excel file called records.xlsx and write the record into the file
4. Check the next record and if it does NOT exist in the database, then check if records.xlsx already exists then open it and write it into it.
[Code]....
Hopefully its clear, sorry if its not, I'm a bit of a novice at this. Is this a good way to do it? Does anyone know of any tutorials that might outline how to open an existing file and write to it?

// Pass the Select command to the adapter.
