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.
Background
A log file contains a mix of timestamps, error codes, and status messages in a single array.
Problem
Need to isolate only the numerical error codes for statistical analysis.
How to use
Paste the log array, select 'Integers' as the extract type, and click process.
Outcome
A clean list containing only the integer error codes, ready for import into a spreadsheet.
Background
A user submitted a form resulting in an array containing empty strings, null values, and valid text.
Problem
Need to remove nulls and trim whitespace to prepare the data for a database.
How to use
Paste the array, select 'Strings', ensure 'Include Null Values' is unchecked, and enable 'Trim Whitespace'.
Outcome
A sanitized array of strings with all empty or invalid entries removed.
