File Formats that Include Field Formats

Anne's suggestion works very well for me as well.

But for new files being imported for the first time, I have had some success in change the file extension of the CSV file to .TXT

Then open Excel first and then use the file open commands to locate the .TXT file (you will have to change the file type drop down from "All Excel Files..." to "Text Files..."

The Text Import Wizard will start automatically when opening a .TXT file.

On Step 1 select "Delimited"
If your file has page header text, you may need to select a starting row for the import (either your column header row if one exists or the first data row).

On Step 2 Select "Comma" for the delimiter (assuming you did start with a .CSV file).

On step 3 you can click on the various columns and identify some basic formats (General, Text, or Date) or to skip a column. If you have an identifying number that exceeds Excel's number place values (15 digits), select text for that column to prevent truncation (or to preserve leading zeros). Also, dates sometimes come across as text if you don't select the Date format.

Further to my comment, I should specify to copy and paste VALUES, of course.

I spend my days working with CSV and SAP files. I use them to create reports or gather information for reports. What I've done is create an excel spreadsheet formatted to my specifications, using the CSV data, initially. (I often use Excel Tables, as they maintain the formatting even when data is added below the last row.) I then copy and paste the data from the CSV file to the formatted spreadsheet - omitting the column headers as they would already exist in the formatting spreadsheet from previous reports. The CSV data automatically take on the formatting of the existing spreadsheet. For instance, the SAP file I use repeatedly have lots of numbers with leading zeros - like so - 00000000240. When I drop this into my formatted spreadsheet, it appears at 240, with no additional manipulation needed. Magic!
