Vovsoft Merge XML Files: Combine Several XML Files into One, in Two Clicks
Merge XML Files is a $19 Windows program from Vovsoft that joins several XML files into one XML document: add the files, click Export Combined XML, done. It's deliberately minimal, with no settings to learn. It runs on 64-bit Windows only. The $19 is a one-time lifetime license, and the free trial works fully for personal use.
It's for people who get data split over many XML files, such as daily exports, catalog parts or feed chunks, and need a single file to import, upload or process, without writing a script.

Overview
Merge XML Files is a small window with two buttons, Add XML Files and Export Combined XML, and a list of the files you've added, by full path. There's also a File menu and, since version 1.2, a right-click menu on the list. Vovsoft itself calls it a merger with "minimalist functionality", and that's accurate: there are no options for how the files are combined.
Features
Two-click merging
Merge XML Files needs only the file list and a click on Export Combined XML to produce the merged file. There are no mappings, XPath expressions or settings to get wrong.
Drag and drop
Merge XML Files accepts files dragged from File Explorer (since version 1.2) as well as the file dialog, so selecting a whole folder's worth of XML and dropping it in works.
Handles files with a DTD
Merge XML Files 1.5 fixed a "DTD is prohibited" error, so XML files that start with a document type declaration now merge too. Version 1.3 improved the merge algorithm itself.
Offline and portable
Merge XML Files runs on your PC, so confidential data never goes to an online merger, and the portable edition runs from a USB stick without installing.
Benefits
Combining XML by hand means copying the inner records out of each file, removing duplicate headers and root tags, and hoping nothing breaks. Scripts and XSLT do it properly but need a developer. Merge XML Files turns it into a job anyone in the office can do in a few seconds.
Real-World Uses
- Joining daily or monthly XML exports from business software into one file for a report.
- Combining catalog or product feed parts before uploading them to a shop or marketplace.
- Merging several XML data files before converting them to a spreadsheet.
- Putting split configuration or data files back together.
Who It's For, and Who Should Skip It
Merge XML Files suits Windows users who now and then need several XML files of the same structure as one file, and want the simplest possible tool for it.
Skip it if you're on 32-bit Windows (it's 64-bit only), if you need control over the merge, such as choosing the root element, merging by key or removing duplicates, or if your files have different structures. An XML editor, XSLT or a short Python script handles those cases, and developers can do the simple case for free too.
Usage Guide
- Download the installer or portable edition and start Merge XML Files.
- Click Add XML Files and select your files, or drag them into the list.
- Check that the list holds the files you want, in full.
- Click Export Combined XML to save the merged file.
- Open the result in your XML editor or target program to check it.
Before you buy
The trial has every feature, with a nag screen, and is for personal use; work use needs the license. Because there are no merge options, the result's structure is whatever the program produces: merge a few of your real files in the trial and check that the combined file is what your target program expects. One license covers one person on any number of their own computers. Vovsoft's general policy is no refunds, since the trial comes first (it may refund an order made by accident, at its discretion, and PayPro Global has the final say on orders it handles).
Where it falls short
- No settings at all: no choice of root element, sorting, de-duplication or merging by key.
- No "add all XML files in a folder" command; it's the only open request on Vovsoft's feature page. Drag and drop is the workaround.
- 64-bit Windows only.
- A middling 3.8 out of 5 on Vovsoft's own site, with no comments explaining it.
What Users Say
On Vovsoft's site
Merge XML Files' product page shows 3.8 out of 5 from 8 ratings, with no written comments, so there's no way to tell what the lower ratings were about. We found no independent reviews; download sites only repeat the vendor's description.
Vovsoft as a company has a TrustScore of 4.6 out of 5 from 411 reviews on Trustpilot (read through a summarizer), with no recent review naming this program.
Vovsoft released four updates in 2025, including the improved merge algorithm and the DTD fix, so the program is still maintained. With no written feedback, test it on your own files.
Comparisons
Merge XML Files vs a script or XSLT
A Python script or XSLT stylesheet is free and can merge exactly the way you want, but someone has to write it. Merge XML Files needs no code, at the cost of having no options.
Merge XML Files vs online XML mergers
Online mergers are free for small files but mean uploading your data, often with size limits. Merge XML Files works offline with no limits once licensed.

FAQs
Does Merge XML Files work on 32-bit Windows?
No. Merge XML Files has been a 64-bit program since version 1.1, so it needs 64-bit Windows.
Can Merge XML Files remove duplicate records?
No. Merge XML Files only combines the files; it has no de-duplication or merge-by-key options.
Can I add a whole folder of XML files at once?
Not with a folder command yet. Select all the files in File Explorer and drag them into Merge XML Files instead.
Is the $19 a subscription?
No. Merge XML Files' $19 is a one-time payment for a lifetime license with future updates. Nothing renews.
System Requirements
- 64-bit Windows 11, 10, 8/8.1, 7, Vista or XP
- About 3.6 MB for the installer, or 2.5 MB for the portable edition
- English interface
Conclusion
Merge XML Files is worth $19 only if you regularly need to combine XML files of the same structure, can't or don't want to write a script, and are happy with the program's one way of merging. The reason not to buy it: it has no options at all and a middling 3.8 rating with no explanation, so anything beyond a simple join needs a real XML tool. Merge a few of your own files in the trial and check the result before paying.
