Overview

The Array Element Counter is a versatile utility designed to analyze datasets by calculating the frequency of elements within an array. It provides flexible counting modes, statistical insights, and multiple output formats to help you quickly identify patterns, duplicates, or specific item occurrences in your data.

How it works

1Paste your list of elements into the input area and select the appropriate delimiter used in your data.
2Choose a counting mode, such as 'Count All', 'Unique Only', or 'Duplicates Only', to filter your results.
3Configure your sorting preference and select your desired output format, such as a table, JSON, or CSV.
4Click the process button to generate your frequency report, including optional statistical summaries.

Use cases
