    How to use Excel Workbook Inspector

    1. Choose a supported XLSX workbook.
    2. Inspect stored sheet, cell, formula, merge and visibility records.
    3. Review the report without treating stored values as freshly calculated results.

    Example: Excel Workbook Inspector

    Inspect a stored value and formula.

    You add
    Macro-free XLSX with A1 stored as 2 and B1 containing formula A1+3 with cached value 5.
    You get
    The report lists A1 as stored value 2 and B1 with its saved formula A1+3 and cache 5, without computing a new result.

    A stored formula and its cached result differ

    An XLSX can contain a formula plus a saved result from an earlier calculation. This inspector reports supplied workbook evidence without updating that cache. Open and recalculate in a spreadsheet application if the task requires a fresh result.

    Workbook metadata can reveal hidden content

    The report can help review saved sheets, cell counts, formulas and supported workbook properties. A hidden sheet is still part of the file. Inspection does not remove those records or certify that the workbook is safe to share. Keep a private original and review the actual content before distribution.

    Questions about Excel Workbook Inspector

    Does inspection recalculate formulas?

    No. It displays stored formulas and any supported cached data.

    Can a sheet dimension be outdated?

    Yes. The declared dimension can differ from the stored cells; inspect both measures.

    Does a hidden row protect its data?

    No. Hidden rows and columns remain in the workbook and can be inspected.
