About this Gig

Need help cleaning, processing, or analyzing messy CSV or Excel data?

I can turn your raw data into clean, structured, and usable results using Python and pandas.

I can help with:

  • Cleaning missing, duplicate, or inconsistent data
  • Formatting and restructuring CSV/Excel files
  • Filtering, sorting, merging, and transforming datasets
  • Calculations, summaries, and basic statistical analysis
  • Creating charts and visualizations
  • Writing reusable Python/pandas scripts for repetitive tasks

You will receive clean and organized output files, with Python source code included when selected in your package.

Please note: The Basic package is intended for one simple CSV or Excel file with straightforward cleaning or formatting requirements. Larger datasets, multiple files, complex transformations, automation, or custom analysis may require a Standard/Premium package or a custom offer.

If you are unsure which package fits your task, please contact me before ordering and briefly describe your data and desired output.
