Change Property Type from Object to String in Kapa.ai Event
kapa.ai a property has been attached to an event, it was an object. It is now being passed as a string. How can we change the property to be of type String instead of Object going forward?

To change a property from Object type to String type in Mixpanel going forward, you have a few options:
Modify Your Implementation
The most direct approach is to modify how you're sending the data to Mixpanel: 1. Update your tracking code: Instead of sending the property as an object, convert it to a string before sending it to Mixpanel. For example, if you're using JSON.stringify() to convert your object to a string.2. Maintain consistency: As mentioned in the documentation, it's a best practice to "keep a property's data type consistent during implementation to avoid any confusion" Build Your Tracking Strategy.
Using Lexicon for Data Governance
If you need to maintain backward compatibility or can't immediately change your implementation, you can use Mixpanel's Lexicon to manage how the property is displayed: 1. You can set up property definitions in Lexicon to help standardize how the property is interpreted in reports.2. While this won't change the underlying data type of incoming data, it can help with consistency in reporting.
Typecasting in Reports
For analysis purposes, you can typecast the property in Mixpanel reports: 1. When using the property in a report, you can use the "Data Type" option in the overflow menu for property filters and breakdowns to force the property into the String data type.2. As noted in the documentation: "Typecasting is helpful when one of your properties is a number but is sent to Mixpanel as a string and you want to see histogram data for that property" Typecasting.Remember that Mixpanel supports five primary data types (String, Numeric, Boolean, Date, and List), and while Objects are supported, they have limited functionality in the UI. The documentation recommends using the five non-object data types for most use cases as they are fully supported in the UI Supported Properties Data Type.

Can I force a property to forever be cast as a string vs an object
Let me check the knowledge base for you again. One moment! đź“š
Based on the knowledge sources provided, there isn't a direct way to permanently force a property to always be cast as a string instead of an object in Mixpanel's data storage. However, you have several options to address this situation:
1. Modify Your Implementation
The most reliable approach is to change how you send data to Mixpanel by ensuring the property is always sent as a string in your tracking code.
2. Use Typecasting in Reports
You can typecast the property to a string in each report: - Use the "Data Type" option in the overflow menu for property filters and breakdowns to force the property into the String data type - This is a report-level change and doesn't affect the underlying data storage - As mentioned in the documentation: "Typecasting is helpful when one of your properties is a number but is sent to Mixpanel as a string and you want to see histogram data for that property" Typecasting
3. Create a Custom Property
You could create a custom property that converts your object property to a string: - Use Mixpanel's custom property feature to define a new property that casts your object property to a string - This would apply the transformation whenever the property is used in reports
4. Consider Property Blacklisting
If this is a default property, you might be able to use property blacklisting to prevent it from being captured, and then track it separately as a string: LBKSmixpanel.init("YOUR_TOKEN", { property_blacklist: ['your_object_property'] });LBKSBlacklisting Default PropertiesNote that none of these approaches will retroactively change historical data that's already been collected. They only affect how new data is collected or how existing data is displayed in reports.
