Count List Items

    Count list items, lines, words, unique values, duplicates, frequencies, characters, and numeric statistics from pasted text.

    When line breaks are present, each line break marks an item boundary. Commas inside a line are not split while auto delimiter is selected.

    Count items, lines, words, and duplicates

    Use this list counter to analyze pasted rows, spreadsheet columns, keywords, tags, email lists, IDs, or plain text.

    • Count total items, unique values, duplicated values, and duplicate occurrences.
    • Switch between line/item mode and word-frequency mode.
    • Choose newline, comma, semicolon, tab, or custom delimiter.
    • Filter the frequency table and export CSV, TXT, or JSON.
    • Show numeric statistics when most items are plain numbers.

    Frequency table

    The frequency table shows each distinct value, its count, and its percent share. This helps spot repeated emails, common tags, repeated SKUs, or dominant words in a short text sample.

    p_i is the percentage share, f_i is the count for one value, and N is the total count after parsing.

    Parsing limits

    The tool is a browser text utility, not a full spreadsheet engine. Quoted CSV, escaped delimiters, and semantic entity matching require dedicated data tools.
