I trust Dataloader.io every day to load and export data in support of our Salesforce.com instance, and our sales reps trust me to insert new data accurately and in a timely fashion. Without Dataloader.io to support our ETL processes, I don't know what I would do. Dataloader.io makes mapping fields extremely easy- and although performing bulk tasks in a live environment is always nerve-wracking, I am supremely happy to report that if anything should ever go wrong when upserting data I have only myself to blame.
I use Dataloader.io both at my job, and as a consultant, for non-profit and for-profit institutions alike. My hat's off to Mulesoft for putting together a great program that I can trust. Despite bad apples in the world of software, I feel that Mulesoft and Dataloader.io in particular are examples of success that live up to their promises.
Thank you Mulesoft for providing us with such a great tool!
