My input data looks like this:
| Date From | Date To |
| 2020-08-14 | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
And I am trying to write something that would fill in the missing columns, to the end of each monthly period, so my target would look like this:
| 2020-08-14 | 2020-08-31 |
| 2020-09-01 | 2020-09-30 |
| 2020-10-01 | 2020-10-31 |
| 2020-11-01 | 2020-11-30 |
| 2020-12-01 | 2020-12-31 |
| 2020-01-01 | 2021-01-31 |
| 2020-02-01 | 2021-02-28 |
| 2020-03-01 | 2021-03-31 |
| 2020-04-01 | 2021-04-31 |
Any ideas?
