- Equal (=)
- Plus (+)
- Minus (-)
- At (@)
- Tab (0x09)
- Carriage return (0x0D)

When filtering these special characters, care should be taken to ensure that not only the special characters in the first position are removed (for example in +-@=cmd|' /C calc.exe'!'A1'). Instead, all leading special characters up to the first legitimate character should be removed.

As an alternative to the above-mentioned filtering, OWASP suggests also another sanitization method which includes three steps (https://owasp.org/www-community/attacks/CSV_Injection).
