Tool usage guide
The Zip Arrays tool allows you to merge multiple JSON arrays by their index, creating a new array of grouped elements using the reliable lodash _.zip logic.
Background
I have two separate lists: one containing user names and another containing their respective account IDs.
Problem
I need to combine these into a single list of pairs to import into a database.
How to use
Paste the names array into Array 1 and the IDs array into Array 2, then run the tool.
Array 1: ["Alice", "Bob"], Array 2: [101, 102]Outcome
[["Alice", 101], ["Bob", 102]]
Background
I am processing two arrays where the second array is missing a value for the final entry.
Problem
I need to maintain the index structure without breaking the alignment of the data.
How to use
Input the arrays into the tool; it will automatically handle the length mismatch.
Array 1: ["A", "B", "C"], Array 2: [1, 2]Outcome
The tool will continue to group elements until the longest array is exhausted, filling any missing indices in shorter arrays with null.
You can provide between two and four JSON arrays to be combined simultaneously.
Yes, the tool expects valid JSON array syntax, such as ["a", "b"] or [1, 2, 3].
Yes, it utilizes the lodash _.zip function to ensure consistent and predictable grouping behavior.
Yes, the tool supports any valid JSON data types, including numbers, booleans, and strings within your arrays.
[["A", 1], ["B", 2], ["C", null]]
