24 time conversion on custom column under Power Query - getting error

Will you please attach a sample Excel workbook? We are not able to work with or manipulate a picture of one and nobody wants to have to recreate your data from scratch.

1. Make sure that your sample data are REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

2. Make sure that your desired results are also shown (mock up the results manually).

3. Make sure that all confidential data is removed or replaced with dummy data first (e.g. names, addresses, E-mails, etc.).

4. Try to avoid using merged cells as they cause lots of problems.

Unfortunately the attachment icon doesn't work at the moment, so to attach an Excel file you have to do the following: just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.

Please pay particular attention to point 2 (above): without an idea of your intended outcomes, it is often very difficult to offer appropriate advice.

I would keep the data and time not split but in the same column. Then I would apply the Number.From(#datetime([Column])) and then split the column to show the date number and the time number (the decimal). Then run your if statement on the number (decimal)

When I bring your table into PQ as a new query, it automatically reformats the time to a decimal. I tried to load the original data but that apparently came from a different file to which I didn't have access. For me to help you it will be necessary to have the original or a simulation of the original to upload.

I am unable to reproduce your issue. When I add your file to PQ, it automatically reformats the Time to a decimal, which is what you want to be able to do with your file. See the picture showing the file in PQ.

Please try

= if [Column5.2] < #time(12,0,0) and [Column5.3] = "PM" then [Column5.2] + #duration(0,12,0,0) else [Column5.2]

time to compare with time, and duration when calculate with time
