Hi @TantirigamaThilina-7057,

Per my research and testing, there is no JSON that can set character limits for multi-line text column values . However, you can use the following JSON to limit the number of characters displayed in the list:

{  
   "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",  
   "elmType": "div",  
   "txtContent": "=substring(@currentField, 0, 10) + ''"  
}

My test result:
