Tired of the frustrations of searching Excel files?

Standard grep only shows raw, unformatted text

Without cell background colors, struck-out items, or visual layout, you can't tell what is active vs. obsolete without opening every file.

Shapes, text boxes, and comments get ignored

Crucial design notes, flowcharts, and warning callouts placed in shapes are frequently missed by conventional search tools.

Opening 50 Excel workbooks freezes your PC

Launching Excel for dozens of search hits eats memory and wastes precious investigation time.

Complex cross-table formulas slow down reviews

You need to know whether the searched term is a raw value, a calculated result, or hidden in a header/footer.
