EmEditor Professional (2026 Edition)

The undisputed performance leader for large file manipulation. Optimized for modern CPUs (AVX-512), it can open files up to 16TB. Its CSV mode features pivot tables, multi-threaded sorting, and regex filtering that remains fluid even with billions of rows. Its main drawback is the subscription-only model for updates and its Windows-only architecture.
