CSV File Not Opening Correctly in Excel: 4 Cases with Solutions
In this section, I will show you some quick and easy methods to solve the issue that the CSV file is not opening correctly in Excel on the Windows operating system.

Case 1: CSV File Is Opening in One Column
When we open a CSV file in Excel, that file may not be distributed to the columns. This happens when the delimiter is not properly set up. In this section, we will see probable solutions to the issue: Excel is opening CSV files in one column.
- Now, we have opened the CSV file in Notepad, which shows the data are comma delimited.
- However, if we open it in Excel, the data will be in column A
Now, let us demonstrate the possible solutions to this problem.
Solution 1: Change Regional Settings
In the first solution, we will change the regional settings from the Control Panel. Mainly, we will change the list separator from semicolon (;) to comma (,). We will be using Windows 10 to demonstrate this process. However, it should be similar to other versions of Windows.
📌 Steps:
- Firstly, open the Control Panel.
- Secondly, click on Clock and Region. Make sure, view by category is selected. Otherwise, you will need to select Region.
- So, a new window will appear.
- Thirdly, select Change data, time or number formats under the Region section
- Then, the Region window will pop up.
- After that, select “Additional settings…”.
- So, the Customize Format window will appear.

Solution 2: Specify Delimiter by Editing the CSV File
If Excel can recognize the data separators, it can show them in multiple columns. In order to identify the delimiter in Excel, we will insert a single line in this solution. The syntax is “sep=delimiter”. We have used a tab in our file, so we will need to add a tab in place of the delimiter.
📌 Steps:
- To begin with, we can see the data file is semicolon-delimited.
- After that, open that file in a text editor. We have opened it in Notepad.
- Then, insert the following lines at the top. If the delimiter were a comma, then we would have written “sep=,”. So, change it according to your needs.
sep = ;
- Afterward, if we open that file in Excel, the data will be in multiple columns. Thus, we have shown you the second solution to the problem: Excel opens CSV files in one column.
Solution 3: Specify Delimiter While Importing CSV File to Excel
In this method, we will import the data from the CSV file into Excel. This solution should work if the other two do not work for you. The importing feature of the CSV file is on the Data tab, and from there we will use the From Text/CSV option.
📌 Steps:
- Firstly, from the Data tab, select From Text/CSV.
- So, the Import Data window will appear.
- Secondly, navigate to the file location.
- Thirdly, select the CSV file and press Import.
- Then, another window will pop up.
- Afterward, from the Load dropdown menu, select “Load”.
- So, this action will import the CSV data into Excel. Moreover, we can see our parser from the second solution is still there. You can simply delete row 5.
