Tool usage guide
The Invert Object tool allows you to quickly swap the keys and values of a JSON object using the reliable lodash _.invert method. This utility is essential for developers needing to perform reverse lookups or restructure data mappings efficiently.
Background
I have a status map where IDs are keys and status names are values, but I need to find the ID based on a status string.
Problem
Manually flipping a large object is error-prone.
How to use
Paste the status object into the input field to instantly generate the inverted map.
{"100": "Pending", "200": "Success", "400": "Error"}Outcome
{"Pending": "100", "Success": "200", "Error": "400"}
Background
I have a mapping of category IDs to category names and want to see if any names are reused.
Problem
Identifying which IDs share the same category name.
How to use
Input the category object; the inverted result will show which IDs were overwritten due to duplicate values.
{"cat1": "Electronics", "cat2": "Home", "cat3": "Electronics"}Since keys in a JSON object must be unique, the last key encountered for a specific value will be the one preserved in the output.
The tool performs a shallow inversion. Nested objects will be treated as string values and may not produce the desired structure.
This tool utilizes the standard lodash _.invert function for consistent and predictable results.
Yes, in JavaScript objects, keys are converted to strings, so the inverted values will become string keys in the output.
No, the inversion process happens locally in your browser for maximum privacy and speed.
Outcome
{"Electronics": "cat3", "Home": "cat2"}
