Tool usage guide
This tool removes all occurrences of specified values from an array using the lodash _.pull method. It accepts JSON arrays for both input and values to remove, with an optional case-insensitive matching feature for strings.
Background
An IoT system collects temperature data, but some sensors send invalid readings like -999 that skew results.
Problem
The array contains erroneous values that need removal for reliable analysis.
How to use
Enter the sensor readings array in the 'Array' field and specify [-999] in the 'Values to Remove' field.
Array: [22.5, -999, 23.1, -999, 24.0], Values: [-999]Outcome
The tool returns [22.5, 23.1, 24.0], with all -999 values removed.
Background
A forum maintains a list of usernames, and moderators need to remove banned users' names, ignoring case variations.
Problem
Banned usernames appear in different cases, making manual filtering inefficient.
How to use
Input the username array and the list of banned names. Uncheck 'Case Sensitive' to catch all variations.
It removes all instances of specified values from an input array using lodash _.pull.
No, both the array and values must be valid JSON arrays.
Yes, string matching is case-sensitive by default; uncheck the option for case-insensitive removal.
Any JSON-compatible values, such as numbers, strings, or objects.
No, it returns a new array with the specified values removed, leaving the input unchanged.
Array: ['Alice', 'bob', 'BOB', 'Charlie'], Values: ['bob'], Case Sensitive: falseOutcome
The result is ['Alice', 'Charlie'], with both 'bob' and 'BOB' removed due to case-insensitive matching.
