reading an excel spreadsheet
is it possible to read data from an excel spread sheet in C++?
I need to read data from a spread sheet and analyze the data.

I know there are ways (I used to write data to spreadsheets all the time, but never read from one), but how often are you going to be doing this? If it is only once, I suggest you save the data in tab or comma delimited format and process it that way. It is very inefficient to read/write data into/out of out-of-process objects.

It is actually a large data file that i wil be getting from someone else.
Anyway how do we write data to a excel sheet. i think i will be asked to output data to excel spread sheet.

The code I used for that was in VB, so I don't expect it to be very valuable in this forum. I imagin there are examples on the web, but the biggest problem I ever had was in finding documentation for the calls (actually, I never did find any documentation).
As an aside, I believe you can create an ODBC link to an Excel spreadsheet, you may want to look at that idea also.

The easiest way is .csv files. these are excel files where the cells are seperated by commas. Can be viewed in notepad or excel.
Not good for complex formulars....

This is the easiest way to go if .csv files are not complex enough (AFAIK) but will require the PC to have a DSN or FILE DSN added.
Look at the MFC CRecordSet class if you have a standard sheet.
