How to use this office tool

Choose an Excel workbook and select a worksheet.
Set the preview size, then extract stored formula cells.
Review formula addresses and download the CSV inspection report.

What this tool does

The viewer reads stored formula expressions from workbook cells and exports each formula with its address and cached result when available.

Formula-bearing cells → address, formula text, cached value → new CSV report

Formulas are inspected, not recalculated with the Microsoft Excel calculation engine. Cached values may be missing or outdated.

Supported formats

Files are processed in memory on this device. Large or structurally complex workbooks may require desktop spreadsheet software.

Input	Support
XLSX / XLS	Parsed locally with SheetJS CE
CSV / TSV	Not recommended; formula metadata is unavailable
Limits	25 MB per file, bounded preview, up to 500,000 used cells

Tips for better results

Save the workbook in Excel before inspecting cached values.
Review external links and volatile formulas separately.
Do not assume cached results are current.

FAQ

Can this tool recalculate Excel formulas?

No. It extracts stored formulas and cached results but does not reproduce the Microsoft Excel calculation engine.

Does the formula report include cell addresses?

Yes. Every row includes the worksheet name, cell address, formula expression, and cached value when available.

Can formulas from CSV files be inspected?

CSV has no native formula metadata. Use an XLSX or XLS workbook for reliable formula extraction.

Are hidden worksheet formulas included?

Formulas in the selected sheet's used range can be listed even when their rows or columns were hidden in Excel.

Is it safe to open formula text in the preview?

The interface inserts formula text with textContent, so it is displayed as text and is not executed as HTML.
