I have a collection of customer records sitting in a series of Excel/CSV files. I need each file brought into a clean, consistent format, with obvious errors corrected and missing values flagged or imputed where possible. Once the data set is tidy, I want a concise analysis that surfaces the key insights: basic demographics, purchase behaviour trends, and any notable correlations you can uncover. Your workflow will cover: • Accurate data entry (where manual transcription or consolidation is required) • Thorough data cleaning—deduplication, standardised naming, out-of-range checks, and validation against any built-in Excel rules • Exploratory and descriptive analysis, delivered as clear tables, summary statistics, and a brief written interpretation. Charts or simple dashboards in Excel, Power BI, or a Jupyter notebook are welcome if they help tell the story. Please keep the process transparent by saving intermediate versions or documenting any transformation steps so I can audit the changes later. The final hand-off should include: 1. The cleaned master spreadsheet in .xlsx and .csv formats 2. A short report (PDF or doc) outlining methods, findings, and recommendations 3. Any scripts, formulas, or notebooks used, with comments for repeatability. If this sounds straightforward for you and you’re comfortable working directly in Excel/CSV (Python or R is fine too so long as output lands back in Excel), let me know your turnaround time and any clarifying questions.
