About Column Splitter
One column holding several values is a common export defect. Split it on a delimiter and each part becomes its own column, appended to the file with names derived from the original header.
A legacy ERP file with a single name field containing "Smith, John" splits on a comma into surname and forename. An address written as "Austin, TX, 78701" splits into three. Every part is trimmed, so the space that follows each comma does not survive into the new columns.
Choose the column, type the delimiter, and set how many parts to create, up to 50. Rows with fewer parts than that get empty cells, which keeps every row the same width for the next tool in your chain.
