Quick formula

Select a cell under a column of numbers and the fx tab offers a Sum, Average, or Count, with the range already picked. Alt+= does the same.

What it does

  • Real Excel files

    Every table saves as an .xlsx workbook that Excel, Numbers, and Google Sheets open with the right numbers already showing.

  • Autosave that stays out of the way

    Every change saves on its own to a folder in Documents. Nothing reopens on launch, and recent tables are one click away.

  • Formulas that keep up

    Change a number and every total that uses it updates. Insert, delete, or move rows and formulas follow along.

  • Quick formula

    Sum, Average, or Count of the numbers above in one click, with the range picked for you and outlined before you choose.

  • A header that stays put

    Row 1 is your header and stays in view while you scroll, so long lists always make sense.

  • Sort and filter

    Sort A to Z or Z to A and filter by value from the arrow in each header. Totals at the bottom stay where they are.

  • Tabs that talk to each other

    A summary tab can add up numbers from other tabs, and renaming a tab updates every formula that uses it.

  • Paste from Excel

    Paste a range from Excel or Google Sheets and keep the values, bold, colors, and number formats.

  • CSV done right

    Leading zeros, ZIP codes, and long account numbers stay exactly as they are, and CSV files save back the way they came.

  • No account, no tracking

    OpusTables works fully offline and never collects data about you or your tables. Export to PDF or CSV any time.
