What does this file merger do?
This browser-based tool combines multiple text-based files into a single output file. It works well for logs, TXT, CSV, JSON fragments, code snippets, markdown notes, exports, and other plain text workflows.
Merge controls included
You can reorder files before merging, insert blank lines or custom separators between files, include file name headers, and remove duplicate lines from the final output.
This makes it useful for building combined reports, merged logs, consolidated notes, or multi-file text bundles.
Private browser-based merging
Your files are processed locally in your browser and are not uploaded to a server. That makes this tool suitable for quick private merging of local text files.
