You cannot add arbitrary custom columns (like "screen_name") directly to the Lexicon data dictionary UI in Mixpanel. Lexicon is designed to manage and describe events and their properties, but it does not support adding new metadata columns beyond what is provided (such as name, display name, description, example value, etc.) Lexicon Overview.However, you can achieve similar outcomes by: - Adding a new event property: If "screen_name" is a property you want to track, you can add it as an event property in your event tracking implementation. Once Mixpanel receives events with this property, it will appear in Lexicon under Event Properties, where you can add a description and example value for clarity. - Using Lookup Tables: If you want to enrich your data with additional attributes (like mapping a user ID to a "screen_name"), you can upload a Lookup Table and map it to an existing property (e.g., user ID). This allows you to use "screen_name" as a property in your reports, even though it is not a native column in Lexicon. Lookup Table columns become available as nested properties for analysis Use a Lookup Table.In summary, while you can't add arbitrary columns to Lexicon itself, you can track new properties or use Lookup Tables to enrich your data and achieve similar results.
