Handy Tool to compare, validate, extract & merge JSONs

Author: | Posted in Angular, Tools 2 Comments

I got into a case where am need to check the keys and the values for the JSON object in our project which is dropped at an even interval with updated key and values.  It is tough to identify the newly updated values and newly added keys ion the latest drop as each json holds huge number keys.  This  VEM JSON tool assists in resolving this issue.

This tool has some unique functionality like extract the non-identical Keys, Values into a separate object by comparing the source and the destination JSON. This saves time and the have high accuracy level compare to manual extraction/merging techniques while working with multilingual JSONs.
