Yes, you can merge event properties with different names (such as "postId" and "PostId") into a single property in Mixpanel using the Lexicon feature. If you change their display name to "PostId" and merge them, Mixpanel will recognize both as a single property for reporting and analysis purposes. This means that when you view your event list or analyze events, both "postId" and "PostId" will appear as one unified property ("PostId").However, it's important to note that this merging only affects how the properties are displayed and queried in Mixpanel; it does not alter the raw data. After merging, the merged property will appear as a single property in reports, and the “Status” column will indicate “Merged.” If you ever need to separate them again, you can unmerge the properties in Lexicon, and they will revert to their original distinct names Lexicon: Merging Data.Keep in mind that Mixpanel strings are case-sensitive, so "postId" and "PostId" are treated as different properties until you merge them Events and Properties Best Practices. Merging them in Lexicon is the recommended way to unify their display and analysis.

No, simply changing the display name of event properties (e.g., setting both "postId" and "PostId" to display as "PostId") in Lexicon will not combine them into a single property for analysis or reporting. Mixpanel is case-sensitive and treats "postId" and "PostId" as distinct properties at the data level, regardless of their display names. They will still appear as separate properties in filters, breakdowns, and queries, even if their display names are identical.To have them function as a single property in reports, you must use the merge feature in Lexicon. Merging combines them for analysis without affecting the underlying raw data. If you only change the display name, it is purely cosmetic and does not unify the properties for querying or analysis Lexicon: Merging Data Events and Properties Best Practices.If you are concerned about the impact of merging, you can always unmerge the properties later, which will restore them as separate properties. But just changing the display name will not achieve the unified behavior you are looking for.

Paras There shouldn't be any issue if you merge. But this approach should work too. You can try this out. No harm in this.
