Actually i have to save changes made on the gridview on the front end to be saved in the data base without using looping so i choose the json stirng option but it is converting the complete table and again saving the complete table to the database this is creating duplicate of data. But i want to catch only those rows which have been updated and edited to be converted to the json strings from json string to sql table

First, it is very difficult to provided assistance when we cannot see the code or understand the design purpose. If you've already saved the data in a table then why do you need the same data in JSON format? Are you trying to keep track of updated and inserted records?

Hi @Sarbanshu Sanyal ,
Please tell us more details of your requirement and the purpose. If you only don't want to loop the database, I think there are no relationship with the json string.
