How Text File Merger Works
Each file you choose is read locally using the File API, then joined together in the order shown in the list, separated by whichever divider you pick.
How to Use This Tool
- Choose or drag in two or more .txt files.
- Reorder them using the up/down buttons if needed, or remove ones you don't want.
- Pick a separator style.
- Select Merge Files, then download the combined result.
Example
Merging chapter1.txt and chapter2.txt with a blank-line separator produces one file with chapter 1's full text, a blank line, then chapter 2's full text.
Helpful Tips
- Use the up and down arrows next to each file to control the final order before merging.
- The Horizontal rule separator is useful when you want a clear visual break between merged sections.
