Files stay on your device

Compare XML files

Find missing, added and changed elements and attributes between two XML files. Formatting differences are ignored, so you only see real changes.

How to compare XML files

  1. Add your two files

    Drop the original and the changed XML file on the boxes below, or paste the XML straight in. You can drop both files at once.

  2. Choose your options

    Decide whether whitespace, letter case or comments should count. You can also skip fields that always change, like timestamps.

  3. Review the differences

    Every change is listed with its exact location, such as /inventory/product[@sku="TEA-002"]. Switch to side by side to see both files lined up.

What Matchcheck does

Matches elements by ID

Elements with an id, name, key or sku attribute are paired by that value, so one deleted record shows as one removal, not a cascade of changes.

Ignores formatting noise

Indentation, line breaks and the order of attributes never count as differences.

Exact locations

Every change shows where it is, like /catalog/book[@id="bk102"]/price, so you can find it in your own file.

Reports you can share

Download an HTML report or a CSV of all changes to send to a colleague or attach to a ticket.

Questions and answers

Are my XML files uploaded anywhere?

No. The comparison runs in your browser. Your files never leave your device, which makes Matchcheck safe for configuration files, invoices and other private data.

Does the order of attributes matter?

No. <item id="1" type="a"> and <item type="a" id="1"> are treated as identical. The order of elements does count, because it often carries meaning in XML.

What happens if my XML is invalid?

Matchcheck tells you which file has the problem and gives the line and column of the first error, so you can fix it and compare again.

How large can the files be?

Up to 25 MB each. Files with tens of thousands of lines usually compare in a second or two.

Can I compare SVG, RSS or config files?

Yes. Any XML-based format works, including SVG, RSS, Atom, KML, GPX, XSD, XSLT, .config and .csproj files.
