Research Data Collection Builder
Define variables, coding and collection rules, then download a data dictionary and blank collection sheet.
Your entries stay in this page’s memory and are not submitted to us. Downloads are generated locally. Reloading or leaving the page clears your entries. Do not enter patient information.
Create a draft structure, not patient records. Define one row’s meaning before using the downloaded sheet; repeated visits usually need a participant identifier and visit field.
CSV files open in spreadsheet software. Inspect imported date formats and category codes before collection. Formula-like text is escaped for spreadsheet safety. This builder does not choose your variables or validate a clinical instrument.
