Overview

The Array Extractor is a versatile utility designed to quickly isolate specific data types from mixed-content arrays. Whether you are cleaning messy datasets or filtering raw inputs, this tool allows you to extract integers, floats, strings, or booleans with precision and ease.

When to Use

  • •When you need to separate numerical values from a mixed list of strings and numbers.
  • •When cleaning raw data inputs that contain unwanted null or undefined values.
  • •When you need to standardize a list of strings by trimming whitespace and filtering by type.

How It Works

  • •Paste your data into the input field as a JSON array, comma-separated values, or one item per line.
  • •Select the specific data type you wish to extract from the dropdown menu.
  • •Toggle optional settings like 'Include Null Values' or 'Trim Whitespace' to refine the output.
  • •Click the process button to generate a clean, filtered list of your desired elements.

Use Cases

Extracting only numerical IDs from a mixed log file containing text and numbers.
Cleaning a user-submitted form list by removing all null and undefined entries.
Isolating boolean flags from a complex configuration object array.

Examples
