Tool usage guide
The Flatten Depth Array tool flattens nested JSON arrays to a specified depth using lodash's _.flattenDepth function. It provides precise control over flattening levels, allowing you to reduce nesting while preserving deeper structures for data processing tasks.
Background
A developer has a nested array from a configuration object.
Problem
Need to flatten only the first level to examine immediate sub-arrays without altering deeper nesting.
How to use
Input the array [1, [2, [3, [4]]], 5] and set depth to 1.
Outcome
The array is flattened to [1, 2, [3, [4]], 5], preserving the innermost structure.
Background
Working with deeply nested data from a JSON file for statistical analysis.
Problem
Require a completely flattened array to compute aggregates or visualize data.
How to use
Enter the array [1, [2, [3, [4]]], 5] and set depth to 3.
depth: 3Outcome
The array is fully flattened to [1, 2, 3, 4, 5], ready for analysis.
You can set the depth from 1 to 10 levels.
The input must be a valid JSON array with any level of nesting.
Yes, it processes arrays containing numbers, strings, and nested arrays.
No, depth is optional and defaults to 2 if not provided.
The tool will return an error; ensure your input is a properly formatted JSON array.
