XML Editor Online: Format, Minify, Check, and Save XML
Use this XML editor to write or inspect XML in a browser-based textarea with line numbers. It checks whether the document is well-formed as you edit and reports an error’s line and column. Format XML for readability or minify it with one click, then use undo and redo, open or save a file, and copy the content you need. Everything runs in your browser.
This XML editor is a browser-based tool for writing, inspecting, and editing XML. Its textarea includes line numbers and live well-formedness checking, so you can work with markup and see where an XML error occurs without switching to a separate editor. You can paste or drop XML into the tool, or open a file to get started.
As you edit, the tool checks whether the XML is well-formed and reports the line and column when it finds an error. Use the one-click Format and Minify buttons to change how the markup is presented, and use undo or redo to move through edits. When you are done, copy the content you need or save it to a file. The editor has no external dependencies, and its stated checks are for well-formedness rather than XML schema validation.
XML represents structured information using markup, including elements that can be nested within one another. Editing XML in a dedicated editor can help make a document easier to inspect, check, or copy into code and configuration workflows. Formatting can make markup more readable, while minifying can create a more compact representation for situations where that is useful.
The XML editor runs entirely in your browser, and your input is not sent to a server. It is free and private, with no server dependency; once the page has loaded, it continues to work offline. Developers and DevOps engineers can use it to inspect unfamiliar XML, check well-formedness, make quick edits, and prepare content to save or copy.
Step 1: Paste or drop your XML into the editor. You can also open an XML file to work with its contents.
Step 2: Review the document in the textarea with line numbers. Check the live well-formedness status as you edit.
Step 3: If an error appears, use its line and column information to find where to inspect the XML.
Step 4: Choose Format to make the markup easier to read, or Minify for a more compact representation.
Step 5: Copy the XML you need or save your work to a file; use undo and redo while editing.
Use case: Inspect an XML document you did not write and find its structure more easily with line numbers and formatting.
Use case: Check whether an XML value is well-formed before writing code that consumes it, and use the reported line and column to locate an error.
Use case: Copy a clean excerpt from a large document without having to work with the entire file elsewhere.
Use case: Format compact or hard-to-read XML so its markup is easier to review.
Use case: Minify XML when you need a more compact representation of the document.
Use case: Open an XML file, make edits, and save the result from the same browser-based editor.
Use case: Use undo and redo while adjusting XML, making it easier to review and revise edits.
