    This tool finds every number in your pasted text (whole numbers and decimals, including negatives) and reports their count, sum, average, minimum and maximum. It is a quick way to total a column of figures, a list of prices or measurements, without opening a spreadsheet.

    Numbers are detected anywhere in the text, whatever separates them (spaces, commas, new lines, or words in between). The result is a small JSON report with the five values, exact for whole numbers and standard floating-point for decimals.

    Everything runs entirely locally in your browser (no upload, even offline) - your text never leaves your device. Only numeric tokens are counted; a thousands separator inside a number is not assumed (write 1000, not 1,000), to keep the parsing unambiguous. Ideal for receipts, invoices, grade sheets, donation totals or laboratory measurement series.

    In 3 steps

    1. Paste your text containing numbers.
    2. Every number is found and totalled.
    3. Download the JSON report (count, sum, average, min, max).

    Limitations: Extracts every numeric token (whole numbers, decimals, negatives) and reports count, sum, average, minimum and maximum as JSON. Group separators are not parsed (use 1000 not 1,000). Decimals use standard floating-point.

    FAQ

    Is my text uploaded?

    No. The calculation runs entirely locally in your browser - even offline. Your text never leaves your device.

    What counts as a number?

    Whole numbers, decimals and negatives anywhere in the text; the surrounding words are ignored.

    Are commas inside numbers handled?

    No. A thousands separator is not assumed, so write 1000 rather than 1,000 for an unambiguous total.

    What is the output?

    A small JSON report with the count, sum, average, minimum and maximum of the numbers found.
