Yes. Your CSV is analyzed entirely in your browser using JavaScript. No data is uploaded to any server — ever. You can verify this by disconnecting from the internet before uploading.
Currently we support .csv files. If your data is in Excel (.xlsx), Google Sheets, or Numbers, export it as a CSV first.
Your grade is a weighted score based on column coverage (30%), data completeness (50%), and data quality (20%). An A means your list is wedding-ready. A C or below means there are gaps that could cause problems.
