I am looking for someone to help me with an Excel file that I have lost the password for. The file extension is .xls and I am open to either resetting or recovering the password. I do have some information about the password, including its length and possible characters used.

- Familiarity with password management software
- Excellent attention to detail and problem-solving skills
