Tool usage guide
The Flatten Array tool uses lodash's _.flatten function to reduce one level of nesting in JSON arrays, simplifying data structures for easier processing and analysis.
Background
A developer receives a nested JSON array from a REST API containing user roles and permissions.
Problem
The nested structure complicates direct iteration over permission objects in the frontend code.
How to use
Copy the permissions array from the API response and paste it into the tool's input field.
Outcome
The array is flattened one level, enabling straightforward looping and rendering of permissions.
Background
Survey responses are stored in a nested array format with categories and sub-answers for analysis.
Problem
Statistical software requires flat arrays to perform calculations and generate reports.
How to use
Input the nested survey array into the tool to reduce its nesting.
Outcome
The responses are flattened, making them compatible with analysis tools like Excel or Python libraries.
Flattening reduces the nesting level of an array by one, converting nested arrays into a single-level array where possible.
Yes, it processes arrays containing numbers, strings, objects, and other arrays without issues.
No, it only flattens one level deep; deeper nested elements remain unchanged.
No, the tool returns a new array, leaving the input array untouched.
It relies on the lodash library's _.flatten function for consistent and reliable array processing.
