.dat file conversion


How to convert a .dat file into a record list which I want to later update in an entity? 

Hello Lakshmishree Umeshwaran,

A .dat file is not a standard data format, so without knowing the contents of the file I really can't say.  If you are able to convert your file into an Excel file, you can use Service Studio to Import Entities from Excel, which will give you what you are looking for.
