Summary
FAQs
Q: What types of files can you work with?
CSV, Excel, Google Sheets, SQL exports, CRM downloads, donor systems, education platforms, social media exports, and mixed-format data.
Can you handle messy or inconsistent data?
Absolutely. Most clients come to me because their data is messy. I specialize in untangling complex, multi-source datasets.
Can you automate this in the future?
Yes. I can structure the final file for PowerBI/Looker Studio and create update workflows using Power Query, Google Sheets, or Zapier.
Will you explain how I can update the file later?
Yes — all projects include documentation and instructions so your team can maintain the dataset without needing a developer.
