I have a csv file which contains several columns of data, one of which is datetime and the rest are various values. There are multiple rows for which the datetime is the same and only one of the rest of the columns is different.

I need to be able to have only 1 row for each datetime and fill in each column. I have done this using Visual Studio with a data table but would like to be able to do the same in something outside of VS.

What I have tried:

I've looked for Python applications but can't find a suitable data table method.

You can read the data into Excel and manipulate it there.

Richard, why?
OP should define what language want to use.

Why not? If it works then it is a solution.

The problem is that is works on my computer but there are so many requirements using VS that it hardly ever works when I send it to somebody else and I was looking for a solution other than VS. Preferably Python.

Were talking about hundreds, if not thousands of rows of data. The person responsible for doing this monthly is doing it that way and it's taking way too much time.

You can manipulate Excel data with pandas or A Guide to Excel Spreadsheets in Python With openpyxl – Real Python[^].

Your requirement is not quite clear. I'd suggest to use pandas.DataFrame[^] with methods:
- read_csv[^]
- drop_duplicates[^].

For example:
#dataframe creation
df = pd.DataFrame({
    'brand': ['Yum Yum', 'Yum Yum', 'Indomie', 'Indomie', 'Indomie'],
    'style': ['cup', 'cup', 'cup', 'pack', 'pack'],
    'rating': [4, 4, 3.5, 15, 5]
#removing duplicates:

    brand style  rating
0  Yum Yum   cup     4.0
1  Yum Yum   cup     4.0
2  Indomie   cup     3.5
3  Indomie  pack    15.0
4  Indomie  pack     5.0

    brand style  rating
0  Yum Yum   cup     4.0
2  Indomie   cup     3.5
