This is a hands-on introductory workshop focused on fostering best practices for data organization in spreadsheets. Participants learn how to organize their data to prioritize clarity, reproducibility, and interoperability, such that they can seamlessly load their data later into an analysis program. The spreadsheet programs covered are Microsoft Excel and Google Sheets. The examples explored are from the field of Social Sciences, but the principles are relevant for any discipline that collects data in spreadsheets. No previous experience with spreadsheets or programming is required.
