I frequently use IT365 Toolbox -- Merge TXT Files Tool, this tool is very practical and simple. Its features and highlights I like:
🛠️Core Functionality
-
Batch Merge Text Files
Supports importing multiple.txt、.csv、Customize File Order
After importing, you can adjust the merged file order using methods such as "Pin to Top," "Pin to Bottom," or dragging and dropping—this is especially important for organizing novel chapters, log timelines, etc.Insert Separators (e.g., Line Breaks)
It can automatically insert a specified number of line breaks between each file's content, preventing content from sticking together and making the structure clearer.Two Download Methods
- Directly Download the Merged Single Text File
