Withdata DataFileConverter merges HTML files into one TXT file locally — any number of files, mapped column by column, with the output options of your choice. 100% local, secure, and cross-platform.
All merging runs on your own computer. Nothing is uploaded to any cloud server.
Millions of rows within a minute. Large files are streamed with low memory usage.
Add two files or a whole folder, then combine everything into a single TXT file.
Files with a different column order or extra columns can be mapped to the output columns before merging.
Native builds for Windows, macOS and Linux, with a step-by-step GUI wizard and a command line interface.
Save a merge session and run it automatically from Windows Task Scheduler or crontab.
