Visible progress and current repair stage.Your documents never leave your computer
Analysis and repair run locally on Windows. Your Excel and Word files are not uploaded to a server or cloud service.
What does the software check and repair?
Word
document.xml, relationships, styles, settings, comments, headers, footers, media, charts and tracked changes.
OOXML
ZIP integrity, CRC, broken XML, .rels files, missing parts, orphaned relationships and Content_Types.
Safe output
The application creates a separate repaired file and does not need to overwrite the original.
Your business file stays on your computer
KR Office Repair Pro is designed for documents that may contain accounting records, customer information, financial reports, production data, employee information, commercial terms, pricing, margins, contracts, logistics data or other confidential business content. In those environments, uploading a damaged workbook or document to an unknown online repair service may be unacceptable.
KR Office Repair Pro performs analysis and repair locally on the user's Windows computer. The damaged Excel or Word file does not need to be uploaded to RepairOfficeFiles.com, an author-operated cloud, or a third-party repair API. The document remains inside the user's local environment.
No document upload
XLSX, XLSM, DOCX and DOCM files do not need to be submitted through a website or repair API.
Local OOXML diagnostics
The internal Office package is inspected directly on the user's computer.
Local repaired output
The repaired document is written to the user's own storage.
Controlled licensing
Only a Hardware ID is supplied to the author when the user chooses to purchase and activate repair functionality.
Analyze your Office file before buying a license
The diagnostic module is free to use and does not require activation. A user can select a supported Office document, run the analysis and review a structured health report before purchasing the repair function.
The report presents severity, a diagnostic code, the affected area and a clear assessment. It intentionally does not disclose a complete technical recipe for manually modifying the internal OOXML package. This gives the customer meaningful diagnostic information while protecting the product's repair logic.
A license is checked only when the user chooses Repair. If the computer is not activated, the application displays its Hardware ID, the licensing contact address, purchase information and a field for entering the issued license key.
What does KR Office Repair Pro analyze?
Modern Microsoft Office documents are not single flat files. XLSX and DOCX are OOXML packages containing multiple XML parts and relationships. KR Office Repair Pro examines several layers of that package and classifies structural issues before a repair is attempted.
Excel diagnostics
- container integrity and required workbook parts,
- worksheet/workbook XML and internal relationships,
- AutoFilter, Freeze Panes, worksheet ranges and dimensions,
- merged cells, styles, tables and defined names,
- data validation, conditional formatting and hyperlinks,
- selected formula anomalies and calculation-chain metadata,
- pivot structures, charts, drawings, media and external links,
- detection of VBA, connections and extended workbook components.
Word diagnostics
- document.xml and document relationships,
- styles, settings, numbering and font information,
- comments and tracked changes,
- headers, footers, media and charts,
- required Word package components,
- VBA project detection,
- internal OOXML relationship consistency.
Why a desktop repair application instead of an online repair service?
Online tools can be convenient for non-sensitive documents. Business files create a different security requirement: control over where the file is processed, avoiding unnecessary data transfers, and keeping the original document under the customer's control.

License, purchase and VAT invoice
The fixed license price is 220 PLN for one computer. The English website displays the current equivalent in USD and EUR calculated using the NBP Table C buy rate. Each license is cryptographically signed and bound to the activated computer.
A VAT invoice can be issued for the license purchase. The buyer can provide company/billing details when requesting a license.
After purchase, the installer can be delivered through an individual one-time download URL. The URL uses a random token, expires after a defined period and becomes invalid after its permitted download has been consumed.
