Combine Raw CDC Files
Bring multiple CDC WONDER downloads into one organized workbook while keeping each raw sheet and its reference context intact.
A research workspace for CDC WONDER
Clean mortality exports, prepare analysis files, and keep research context together.
WONDER Workspace is being built to reduce the repetitive work that sits between CDC WONDER downloads and a manuscript-ready analysis. The goal is simple: preserve the raw data, clean the tables, combine related worksheets, and prepare files for trend analysis without losing citations, caveats, or query context.
