ConvertDocs

Converts the values in the specified columns either to a supported target type or using a custom converter, keeping their original names and positions within the DataFrame.

This function does not immediately convert the columns but instead selects columns to convert and returns a Convert, which serves as an intermediate step. The Convert object provides methods to transform selected columns using:

• to

• with

• asFrame

• perRowCol

• notNull

• toDataFrames

Additionally, it offers a wide range of methods for converting to specific types, such as toStr, toDouble, and many others.

For the full list of supported types, see SupportedTypes.

Each method returns a new DataFrame with the updated columns.

Check out Grammar.

This can include column groups and nested columns.
