Excel data cleanup, input and CSV

Separate rules for future input from cleanup of existing data. Changing how a cell appears differs from deleting values or rows, so plan how to reverse the operation.

Before choosing a task

  1. Save a working copy and check headers, blank rows and merged cells.
  2. Use dropdowns to constrain input, or freeze panes to keep headings visible.
  3. When importing CSV, check leading zeros and automatic date conversion as well as character encoding.
