What Replace XML Keys can do:

Replace XML Keys gives you precise control over renaming elements and attributes in your XML data. You can use it to normalize tag names, adjust for schema changes, or swap out keys before converting to other formats. Enter multiple old=new pairs to perform bulk replacements instantly, and optionally match casing or target attributes too. With no server upload and real-time output, it’s perfect for quick updates and batch changes.

Example:

Input XML:

<note>
  <To>Tove</To>
  <From>Jani</From>
  <Body>Reminder</Body>
</note>

Replacement Map:

To=Recipient  
From=Sender  
Body=Message

Output XML:

<note>
  <Recipient>Tove</Recipient>
  <Sender>Jani</Sender>
  <Message>Reminder</Message>
</note>

Common Use Cases:

Replace XML Keys is ideal when you’re preparing XML for integration with another system, matching new schema standards, or just cleaning up tag names. It’s also handy for transforming attribute-based data, renaming metadata keys, or ensuring consistent naming across datasets. Everything updates in-browser, making edits fast and reversible.

Useful Tools & Suggestions:

Before you start replacing keys, run Extract All XML Keys to see exactly what you’re working with. And once you’ve made changes, Validate XML helps catch any structure issues that might’ve slipped in.
