Tool usage guide
The Flatten Deep Array tool recursively flattens any deeply nested JSON array into a single-level array using lodash's _.flattenDeep function. It handles arrays of any depth and mixed data types, simplifying complex data structures for easier processing.
Background
A developer receives a nested array from a REST API containing user data grouped by categories.
Problem
The array has multiple levels of nesting, making it difficult to iterate over individual user entries.
How to use
Paste the nested array, such as [1, [2, [3, [4]]], 5], into the input field.
Outcome
The tool outputs a flat array [1, 2, 3, 4, 5], allowing easy access to all elements.
Background
Survey responses are stored in a deeply nested JSON array, with answers grouped by question and respondent.
Problem
Calculating statistics requires a flat list of all responses, but manual flattening is error-prone.
How to use
Input the nested survey array, like [[["a", "b"], ["c", "d"]], ["e", "f"]], into the tool.
Outcome
The flattened output ["a", "b", "c", "d", "e", "f"] enables straightforward aggregation and analysis.
It recursively flattens a deeply nested JSON array into a single-level array.
Paste your nested array into the input field and the tool will output the flattened version.
It accepts any valid JSON array with mixed data types and arbitrary nesting depth.
No, it uses lodash _.flattenDeep to handle arrays of any depth recursively.
Yes, it preserves all elements, including numbers, strings, or objects, in the flattened output.
