Unlock Password-Protected Excel Workbook

I have a single Excel workbook that I can no longer open because the file-open password has been forgotten. The sheet holds sensitive company information, so I need someone who can safely remove or recover the password without damaging data, formulas, or formatting. I do have full permission to access the file, but I cannot share its contents publicly; we will arrange a secure transfer once we start.

Please be comfortable working with Excel password-recovery techniques (VBA, Hex editing, specialized tools—whatever you prefer) and be willing to sign a short confidentiality acknowledgement if requested.

Deliverable
• Return the workbook fully accessible with no password prompt, or supply the working password, so I can open it in Microsoft Excel and verify every sheet loads correctly.
