Introduction to the Online List Duplicate Counter

The online list duplicate counter processes a block of line-by-line strings and automatically calculates each list item's occurrence count and frequency. It can be used for data cleaning, keyword deduplication, log analysis, word-frequency counting, and similar scenarios.

It supports automatically filtering blank lines and is simple and convenient to use. If your original data is a string separated by symbols such as commas, vertical bars, or spaces, you can first process it with the String-to-List tool before counting.

How to Use the List-Item Counter

Step 1: Paste each list item, one per line, into the text box.

Step 2: Click the "Count" button, and the tool automatically removes blank lines and analyzes how many times each item appears.

Step 3: The results show each list item, its occurrence count, its percentage frequency, and other information. You can copy the statistics for analysis in Excel or other scenarios.

Bulk Text Duplicate Counting FAQ

Does the duplicate counter support large volumes of data?

Yes, but we recommend keeping it within tens of thousands of lines to ensure a good performance experience.

Can the text counter handle delimiter-separated strings?

This tool does not process delimiters. Please use the "String-to-List tool" first to convert them into line-by-line data before counting.

Will the list-item counter count blank lines?

No. The tool automatically filters out all blank lines or whitespace characters.

Can the bulk list frequency counter export the results?

Yes. The statistics can be exported to an Excel or TXT file with one click.

Will it upload data? Is it safe?

It's processed entirely in the local browser and does not upload to a server, ensuring privacy and security.
