To split data into multiple rows in one row, you can use Excel formulas or programming languages like Python or SQL, depending on your environment. In Excel, the 'Text to Columns' feature under the Data tab allows you to split cell contents based on a delimiter into multiple columns. For more complex data manipulation, Python's pandas library offers the `.str.split()` function, which can expand a column into multiple rows based on a separator, using `expand=True` parameter, and then you can use `.explode()` to turn array-like column contents into separate rows.

- How can I split a column into multiple rows using Python pandas? Use the `.str.split()` function with `expand=True` to split the column into multiple columns, and then apply `.explode()` to transform list-like values into separate rows.
- Is it possible to split data into multiple rows using SQL? Yes, SQL offers functions like STRING_SPLIT (in SQL Server) or unnest with string_to_array (in PostgreSQL) to split string data into multiple rows based on a delimiter.
