Extract data from windows forms

Question

Hello,

I have an old windows forms app made with boardland c++. I need to extract all the contents of that app to transfer it to a web app.

The app is similar to excel, it has columns and rows...and I need to extract that rows and columns.

First aproach is to copy paste, but there are about 1gig of information...it will took days to some "slave" to do it.

I though some windows forms testing framework could extract information, so there must be something to extract that data.

The file with all data is in a unknow format I tried a lot of things nothing found, the original developer must be dead also the win32 app is nasty.
