This combines the contents of several text files into one, with a separator you can customize between each. It's a small but genuinely time saving tool whenever you've got a handful of separate notes or drafts that need to become one document.
How to use it
- Click the file picker and select multiple files, holding Ctrl or Cmd to pick more than one.
- Adjust the separator text between files if you want something other than the default.
- Review the merged result that appears automatically.
- Click download merged text to save the combined file, or use the copy button.
- Select a different batch anytime to merge something new.
When it helps
- Combining several meeting notes into one document for easier searching.
- Merging log files from different sources for a unified review.
- Assembling separate chapter drafts into a single manuscript.
- Combining a few small config snippets into one file.
- Merging exported notes from different apps into a single backup.
Good to know
- Use a clear separator, like a row of dashes made of underscores or plain characters, so it's obvious where one file ends and the next begins.
- Name your source files in the order you want them merged, since file pickers usually list files alphabetically.
- Check the merged output before deleting the originals, in case something needs merging again.
- Preview the merged output before downloading if the source files use different line ending styles, since mixing them can occasionally cause a subtle formatting quirk in some editors.
- If you're merging files that will become one long document, consider adding a short heading before each section manually once merged, for easier navigation later.
Questions
What file types can I merge?
Plain text based files like .txt, .md, .csv, and .json. It reads each file's text directly rather than handling a binary format like a Word document.
Can I control the merge order?
It generally follows the order your browser's file picker returns them, usually alphabetical. Renaming files with a numeric prefix is a reliable way to control the order.
Is there a limit on how many files I can merge?
No fixed limit, though selecting a large number of sizeable files will take a bit longer since it all runs in your browser.
Can I merge files in a custom order rather than alphabetical?
Since file pickers typically return files alphabetically, the most reliable way to control order is renaming files with a numeric prefix before selecting them.
Does merging preserve each file's original formatting?
Yes, each file's content and line breaks stay exactly as they were. Only the separator you choose is inserted between them.
Can I merge files that use different character encodings?
Your browser reads each file as text, which normally handles common encodings fine, but a file with an unusual or legacy encoding could occasionally display incorrectly.
