AutoSplit

🔹 AutoSplit for Excel

Effortlessly divide Excel files into user-specific files — now with full control, enhanced summaries, and smart automation.

📄 Description

AutoSplit is a powerful, user-friendly Excel tool that automatically separates large datasets into individual files based on the value in a selected column — all with just a few clicks. Whether you're working with customer data, sales reports, or departmental lists, AutoSplit helps you quickly segment and export tailored files without writing a single formula or macro.

Now featuring a real-time progress window, plus Pause and Cancel buttons, AutoSplit gives you full control during long or complex operations. With updated confirmation prompts, improved file handling, and a clean interface, it’s more robust and intuitive than ever.

Perfect for automating reports, organizing large data exports, or securely sharing filtered datasets.
