Tool usage guide
The Invert By tool allows you to restructure JSON objects by grouping keys based on their corresponding values. Powered by the lodash _.invertBy method, this utility simplifies data transformation by collecting keys into arrays associated with unique values or transformed property paths.
Background
A developer has a list of users and their roles and needs to generate a list of users per role for a dashboard.
Problem
The current data is structured as {user: role}, but the UI requires {role: [users]}.
How to use
Input the user-role object and run the tool to invert the mapping.
{"Alice":"Admin", "Bob":"Editor", "Charlie":"Admin"}Outcome
{"Admin":["Alice","Charlie"], "Editor":["Bob"]}
Background
An API response contains items with nested status information that needs to be grouped.
Problem
Need to group items by the 'status' property located inside a nested object.
How to use
Input the object and specify 'status' in the Iteratee Path field.
{"item1":{"status":"active"}, "item2":{"status":"pending"}, "item3":{"status":"active"}}Outcome
{"active":["item1","item3"], "pending":["item2"]}
It transforms an object by swapping its keys and values, grouping all original keys that share the same value into an array.
It allows you to group keys based on a specific property path within the values, rather than the values themselves.
Yes, it utilizes the lodash _.invertBy function to ensure consistent and reliable data processing.
The tool will group all those keys into a single array under that value in the resulting object.
Yes, by using the Iteratee Path, you can target specific nested properties to determine how the keys should be grouped.
