What Is a CSV File?
The file which separates values by a comma is called a CSV file. It is a delimited text file. Each line of a CSV file consists of a data record where each field is separated by a comma. We can import or export a CSV file that contains data records in our excel worksheet very easily.
3 Ways to Stop Excel from Auto Formatting Dates in CSV
To explain the methods, we will use a CSV file that contains information about the ID Number and Date of Birth of some employees.
If we open or import this CSV file in excel, we will see a dataset like below.
And after auto-fitting the columns, we will see the result like below.
Here, if we look at the Date of Birth column, we can see excel has auto formatted the dates. It does not match with our original dataset in the CSV file. For example, if we look at Cell C2, it contains 10-Jul-93. But our CSV file contains 10-July-1993. We want to display the CSV file without auto formatting the dates.
