It is possibly the world's most popular CSV Splitter. My CSV Splitter ranks #1 among 920,000 results in Google, Yahoo and other search engines for the search term "CSV splitter". Originally, I wroted it for my friend Gazuz. Who would have thought it was such a big hit? Now i'm maintaining it for the benefits of the world. You can download it free from FxFisherman.com. Like the title says, it runs blazingly fast! A gigabyte file could be splited under a few seconds using minimal memory.
