Tool usage guide
The Compact Array tool removes falsey values from JSON arrays using Lodash's _.compact method. It cleans data by eliminating false, null, 0, empty strings, undefined, and NaN, with options to preserve zeros and empty strings if needed.
Background
A developer has an array from a JSON response containing numbers, booleans, and nulls.
Problem
The array has falsey values that interfere with calculations.
How to use
Input the array [0, 1, false, 2, "", 3, null, 4, undefined, 5, NaN] and click compact.
Outcome
The output is [1, 2, 3, 4, 5], with all falsey values removed.
Background
An IoT application logs temperature readings where zero is a valid value indicating freezing point.
Problem
Need to remove nulls and undefined values but keep zeros for accurate analysis.
How to use
Input the array [23, null, 0, 15, undefined, 0, 12] and check 'Preserve Zeros' before compacting.
Outcome
The output is [23, 0, 15, 0, 12], with zeros retained and other falsey values removed.
The tool removes false, null, 0, empty strings, undefined, and NaN.
Yes, enable the 'Preserve Zeros' option to retain zeros.
Check the 'Preserve Empty Strings' option before compacting.
The input must be a valid JSON array, e.g., [1, null, 2, false, 3].
Yes, the tool returns a new array with falsey values removed, leaving the original unchanged.
