Common issues

File opens with incorrect formatting

The .CSV file may not display correctly if the delimiter used in the file does not match the expected delimiter in the application.

  1. Check the delimiter used in the .CSV file (commas, semicolons, etc.).
  2. Configure the application to use the correct delimiter when opening the file.

Special characters not displaying correctly

Non-standard characters may not render properly if the file's encoding is not supported by the application.

  1. Ensure the file is saved with UTF-8 encoding.
  2. Open the file in a text editor and re-save it with the correct encoding if necessary.

Security note

Open .CSV files only from trusted sources to avoid malicious data.
