We are always searching the AppExchange for handy apps that can help make our clients job's easier. We recently came across the Enabler for Excel and we have to say, it's worth sharing.
The Enabler for Excel is a Microsoft Excel add-on that allows you to perform mass updates, inserts and deletes. You can do this all within Excel and makes data work much easier than using the Data Loader. You can run a Salesforce report out to Excel, make data changes in Excel and seamlessly push it back to Salesforce.
