What does Stellar Repair for Excel do?

Stellar Repair for Excel fixes corrupt .xls, .xlsx, .xltm, .xltx, and .xlsm workbooks and saves the recovered content into a new Excel file. It rebuilds individual objects — tables, pivot tables, formulas, macros, query tables, and conditional-formatting rules like data bars and icon sets — instead of only pulling out raw text. The tool isolates the corruption inside the workbook, removes the damaged elements, and restores the file to a state Excel can open again. A preview pane shows exactly what was recovered before you save, so you can judge whether a badly damaged file is worth keeping.

Which Excel file types and versions does it support?

It repairs five Excel formats — XLS, XLSX, XLTM, XLTX, and XLSM — created in versions from Excel 2000 up to Excel 2021 and Office 365. The repair engine recovers complex chart types including TreeMap, Sunburst, Histogram, Stock, Waterfall, and Box & Whisker charts, not only basic bar or line graphs. It also restores visual objects such as WordArt, SmartArt, Form Controls, and background images. This matters for a damaged financial or engineering workbook that depends on charts and embedded formulas which simpler text-only recovery tools tend to drop.

What is the difference between the Standard, Toolkit, and Technician editions?

The Standard edition repairs Excel files only and is licensed for a single system, while the File Repair Toolkit adds Word, PowerPoint, and PDF repair in the same interface. The Toolkit Technician extends that coverage to repairs across up to three systems at one location. If you only deal with broken spreadsheets, Standard is enough; pick the Toolkit when you also recover corrupt .docx, .pptx, or PDF files, and the Technician tier when you service several machines. The table below summarizes what each tier includes.

What technical limitations or missing features should users know before buying?

Stellar Repair for Excel runs only on 64-bit Windows 11, 10, 8.1, and 8; there is no macOS version and no Windows Server edition, so it cannot be installed on a server operating system. The Standard license covers one system only — repairing Excel files across several machines requires the Technician edition. The interface is English only. One practical constraint: the tool will not begin a repair while Microsoft Excel is open, so you must close all Excel instances first. The free download scans and previews recoverable data, but saving the repaired workbook requires a paid license.

Does Stellar Repair for Excel need Microsoft Excel installed to work?

No. The software repairs corrupt workbooks even on a machine where Microsoft Excel is not installed, because it reads and rebuilds the file structure directly. That helps support technicians who receive damaged files from clients but do not keep every Office version on their own workstation. You must still close any running Excel instances before starting, since the tool blocks the repair when Excel is already open. The repaired file is written as a new workbook with a "Recovered" prefix, so your original corrupt file stays untouched.

Frequently asked questions about Stellar Repair for Excel

Can it recover a worksheet that uses engineering formulas?

Yes. To repair worksheets containing engineering formulas, first enable Excel's Analysis ToolPak add-in via Tools > Add-Ins, then run the repair. The tool also restores standard embedded functions, numbers, group and subtotal data during the same process.

Which Excel corruption errors can it resolve?

It targets common corruption messages such as "Excel found unreadable content in name.xls", "Excel cannot open the file filename.xlsx", "the file is corrupt and cannot be opened", and "file name is not valid". If Excel's built-in Open and Repair has already failed on a workbook, this tool's deeper scan is the recommended next step.
