Other options include ruby's WIN32OLE and DBI libraries. For the former,
you'll have to be running on a machine w/excel installed. You'd use the latter
on a windows machine to read the spreadsheets in via ODBC. Your connect string
would be *something* like:
connection_string = "dbi:ADO:" +
"Provider=MSDASQL;" +
"Persist Security Info=False;" +
"Extended Properties=\"dbq=c:/path/to/spreadsheet.xls\";"

Subject: [Rails] Importing / Parsing Large Excel Files ?
Hello,
I'm running into a project where a client has large Excel files (60.000+
records per file) and he needs an application to import them into a database to
use this data for useful operations (reporting, calculations .. etc).
I know about the available libraries:
http://raa.ruby-lang.org/project/parseexcel/
http://rubyforge.org/projects/spreadsheet/
http://rubyforge.org/projects/roo/
I've used parseexcel before but for small files. The point is that parseexcel
and spreadhsheet libraries have a reputation that they can't handle large excel
files (I don't know about 'roo').
The guy here (http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-
talk/223230) created some kind of a bridge between Ruby and Java to use
'JavaExcelAPI' and it did work fine for him!
Has anyone tried importing large excel files with ruby? Do I really need to use
a Java library through a bridge to get my job done?
Personally I prefer to hire a Java developer to do that Excel importing module
than doing a bridge and correct me if I'm wrong.
What do you suggest guys? Is there some great ruby library to do the job that I
never heard of before? Or do you suggest some tweaks like parsing the Excel
file using 'parseexcel' like 500 records or something at a time?
I'm kinda lost and I need your help
Regards
