Embodiments provide a viewer/editor for schema-less data, such as a NoSQL database. The data structures are displayed so that each entity type in the data uses a different color and variable column widths. This allows the user to identify relationships between entities. For a selected entity, only the properties applicable to that entity are displayed by the viewer/editor. The column width for each property is optimized to reduce confusion and to allow the user to focus on the selected data.
