EmEditor is a fast, lightweight, yet extensible, easy-to-use text editor for Windows. Both native 64-bit and 32-bit builds are available, and moreover, the 64-bit includes separate builds for SSE2 (128-bit), AVX-2 (256-bit), and AVX-512 (512-bit) instruction sets. The text editor supports powerful macros, Unicode, and very large files. EmEditor has won over 24 International awards, including the Shareware Industry Award in the Best Apps category. EmEditor has also earned Windows 10 certification from Microsoft.
I haven't found other editors that can match its capability and ease of use in editing editing CSV file.
