Excel Customer Data Cleansing

I require an experienced data analyst to cleanse my customer data which exists in the form of Excel files. The primary issues anticipated are incorrect entries that need to be identified and rectified.

Ideal Skills:
- High proficiency in Excel
- Detail-oriented and meticulous in data cleanup
- Previous experience in customer data cleansing

Your role would be to:
- Identify and correct inaccurate entries in the data files
- Ensure the corrected data is consistent and reliable for usage

I look forward to a meticulous and in-depth cleanup of this data to improve its usability.
