According to the Mixpanel documentation, the maximum length for a string property value is 255 characters. This limit applies to both event properties and user profile properties.Specifically, the Property Reference states: "String properties have a limit of 255 bytes."It's important to note that different character encodings may require different numbers of bytes to represent a single character. So while the limit is 255 bytes, the actual number of characters may be less depending on the encoding used.If you have longer strings, Mixpanel will truncate them to 255 characters. For cases where you need to send longer strings, the documentation recommends some alternatives: 1. For URLs: Parse the URL and track its individual components (host, path, URL params) as separate properties.
2. For JSON encoded strings: Parse the JSON and flatten it into separate properties.
3. For free text or user-generated content: Consider excluding it if it's not useful for analysis, to avoid accidentally sending over any PII (Personally Identifiable Information).These recommendations can be found in the Import Events documentation.
