Privacy and file handling

Your selected content is processed on your device. SolvePilot does not receive or store the document. Closing the page ends the working session, while downloaded output remains in your normal downloads location.

Formatting and accuracy

File formats describe content differently, so perfect visual reproduction is not always possible. Headings, paragraphs and ordinary tables are generally more portable than custom fonts, floating objects, macros, formulas or complex page designs.

Limitations of this converter

PDF to Word extracts existing text and does not perform OCR on scanned images. Spreadsheet conversion focuses on visible tabular data. DOCX conversion may simplify advanced Word features. Review important output against the original.

Important: Keep the original file and confirm converted figures, text, page breaks and formatting before submission or publication.
