My requirement is, to open existing .xls template, write data to some specific /fixed cells to it and make it available for download.In case if I will use "Excel.Application", then at the time of deployment is it necessary that Server should have Microsoft Office installed?
I'd like to know which are the best practise to easily manipulate excel files.I need to do only simple actions: create new file, add new sheets, populate cells from a dataset and add calculate cell.Is there something build-in visual studio or have I to use some third part tools?
i'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.
Currently i am onli able to get data via columns but due to the formatting going haywire, i gave up on it.
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.
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?
I have a web app where user uploads a file.ile is saved in server locally and I want to read some data from it.Currently my development server has office 2003.So do I need office 2007 in order to be able to read an excel from office 2007 ?
