I have a data set which is set out like the following:
| Service | Charge | Start Date | End Date |
| A | £30 | 01/06/2025 | 31/08/2025 |
| B | £4.50 | 25/05/2025 | 24/06/2025 |
| C | £10 | 14/05/2025 | 13/06/2025 |
| D | £9.50 | 01/06/2025 | 30/06/2025 |
I want to change the data so rather than having start/end dates, each month is a column with the relevant charge for that period showing in the column. How can I do this?
