In accordance with embodiments, there are provided mechanisms and methods for facilitating evaluation of data types for dynamic lightweight objects in an on-demand services environment. In one embodiment and by way of example, a method includes uploading a data file having data at a first computing device in response to a request, and detecting data types relating to the data within the data file. The detecting includes scanning data rows and data columns of the data file. The method may further include classifying the detected data types into one or more categories, and creating one or more dynamic objects based on the one or more categories.
