Update / convert values

Edit pageLast modified: 24 July 2025

Both update and convert can be used to change column values in a DataFrame.

Difference between these operations:

  • convert allows changing the type of the column, update doesn't

  • parse is a special case of convert to convert String into different types automatically based on its contents

  • unfold is a special case of convert to convert DataColumn of objects into ColumnGroup based on properties of objects.

  • update allows filtering cells to be updated, convert doesn't

  • fill is a special case of update to replace missing values
