How do I open Excel files with EmEditor?

Excel files are binary files, and you can’t open Excel files directly with EmEditor. However, there are two ways to copy over your data.

Export CSV file

Open an Excel file in Excel, go to File | Save As and Browse. Save the file as CSV UTF-8 (Comma delimited) (*.csv). The .csv file can be opened in EmEditor.

Copy and paste

Open an Excel file in Excel, press CTRL + A, and CTRL + C to copy all data to the clipboard. Launch EmEditor and switch to CSV mode from the CSV toolbar. If you are using EmEditor v22.0.1 or below, you must use the Tab separated mode. Press CTRL + V to paste.
