Feel free to post links to websites, like www.bettersolutions.com and other databases here. Example: Google Fusion Tables, Microsoft Access, FileMaker for Mac, Alpha Five which specializes in internet ready imports/exports.
Also discuss Comma Separated Value problems here. Sometimes these files are opened and interpreted poorly due to the General Format setting in most spreadsheets. Visit the group to learn work-arounds to various CSV problems.
