Withdata DataFileSplitter splits a large HTML file into several smaller files locally — by object count (a fixed number of records per file) or by column value (one file per distinct value). 100% local, secure, and cross-platform.

Why Choose Withdata DataFileSplitter as a HTML Splitter?

🔒 100% Local & Secure

All splitting runs on your own computer. Nothing is uploaded to any cloud server.

Write a fixed number of records per output file, and get as many files as the data needs.

📌 Split by Column Value

Write one file for every distinct value in a chosen column — one file per account, per region, per day, and so on.

🖥 Windows, macOS, Linux

Native builds for Windows, macOS and Linux, with a step-by-step GUI wizard and a command line interface.

⏱ CLI & Scheduled Tasks

Save a split session and run it automatically from Windows Task Scheduler or crontab.
