What is XML Viewer?

XML Viewer is an Android app for opening, formatting, browsing, searching, and exporting XML documents. It shows XML in a clean tree view with indentation, syntax highlighting, expandable nodes, line numbers, search, bookmarks, and node details.

Who is XML Viewer for?

XML Viewer is built for developers, testers, support teams, students, and power users who need to inspect XML files quickly without turning the app into an editor or a schema tool.

How do I open an XML file on my Android phone?

Open XML Viewer and tap Open XML file. Android will show the system file picker, where you can choose an XML file from Downloads, device storage, cloud storage apps, email attachments, or any app that provides files.

The full walkthrough is in How to open an XML file on Android.

Can XML Viewer open XML files from another app?

Yes. XML Viewer can receive XML files from file managers and other apps that share or open text/xml or application/xml content.

Can I paste XML instead of opening a file?

Yes. Copy XML text to your clipboard, open XML Viewer, and tap Paste XML. The app checks that the clipboard contains XML before opening it in the viewer.

Can XML Viewer load XML from a URL?

Yes. Tap Load from URL, enter a link to an XML document, and XML Viewer downloads and opens it. URL history is saved so you can reopen or refresh recent URL documents.

Can XML Viewer scan a QR code?

Yes. XML Viewer can scan a QR code that contains XML text or a link to an XML file. Camera permission is used only for QR scanning.

Is XML Viewer free?

Yes. XML Viewer is free to download and use. The free version includes the core XML viewer, tree browsing, text search, line jump, basic PDF export, copy actions, and visual customization.

Does XML Viewer have ads?

Yes. The free version may show ads. XML Viewer Pro removes ads.

What does XML Viewer Pro unlock?

Pro unlocks larger XML files, XPath search, copy XPath, JSON export, unlimited PDF export, advanced PDF options, export node as XML, persistent bookmarks and notes, saved expansion state, detailed XML error explanations, reference highlighting, and an ad-free experience.

Is Pro a subscription?

No. XML Viewer Pro is a one-time lifetime purchase. There are no subscriptions or recurring fees.

Does XML Viewer work offline?

Local XML files and pasted XML are processed on your device. You can open, view, search, copy, save, and export local XML without sending the file to a backend. Features that naturally need the internet, such as loading XML from a URL and showing ads in the free version, require a connection.

Do you collect or upload my XML files?

XML Viewer does not upload local XML files for viewing, parsing, searching, or exporting. Local files are processed on your device. If you use Load from URL, the app connects to the URL you entered to download that XML document.

What is the largest XML file XML Viewer can open?

The free version supports XML files up to about 2 MB by default. Pro removes that free limit and enables large file handling, but the practical maximum still depends on your device's available memory. The app also uses a safety limit to avoid opening files that are too large for the device to handle reliably.

What happens if a file is too large?

Free users are shown an upgrade prompt when a file is over the free size limit. If a file is too large for the device to open safely, XML Viewer shows a friendly error instead of crashing.

Does XML Viewer edit XML files?

No. XML Viewer is read-only. It does not edit the original XML file in place. Save, share, and export actions create a new formatted file or export output.

Does XML Viewer format or pretty-print XML?

Yes. XML Viewer formats XML into a readable structure with indentation, syntax highlighting, line numbers, and expandable nodes. You can save or share the formatted XML.

Can I expand and collapse XML nodes?

Yes. Tap nodes to expand or collapse them. You can also expand all or collapse all from the viewer toolbar.

Can I search inside an XML file?

Yes. Free text search looks across element names, attributes, and values. Results can be opened from a results sheet, and next/previous buttons move between matches.

Can I search by XPath?

Yes, with Pro. XPath search lets you enter an XPath query and jump directly to matching nodes. Invalid queries are shown as friendly errors.

Can I jump to a line number?

Yes. Tap the line jump action, enter a 1-based line number, and XML Viewer scrolls to that line and highlights it. Line numbers stay stable even when parts of the tree are collapsed.

What can I see in node details?

Long-press a node to open node details. The sheet shows the node name, type, depth, child count, attributes, text value, XPath, parent information, bookmarks, notes, and copy/export actions.

Can I copy XML data from a node?

Yes. You can copy a node as XML, JSON, or plain text. You can also copy individual attribute values and text values.

Can I copy the XPath of a node?

Yes, with Pro. Open node details and use Copy XPath to copy the full XPath for that element.

Can I bookmark XML nodes?

Yes. You can bookmark nodes from node details and open the bookmarks sheet from the viewer toolbar. Free bookmarks last for the current session. Pro bookmarks are saved per file.

Can I add notes or annotations to nodes?

Yes. Node details include annotation tools for marking nodes with colors and notes. Pro saves bookmarks and notes per file so they are available when you reopen the same document.

Can XML Viewer show file properties?

Yes. File properties show metadata and XML structure details such as file name, size, source URL when available, root element, encoding, total elements, unique element names, attributes, text nodes, and max depth.

Can XML Viewer export XML to JSON?

Yes, with Pro. XML Viewer exports the full XML document as formatted JSON. Attributes are stored under @attributes, text values use #text when needed, repeated elements become arrays, and empty elements become null.

Can XML Viewer export XML to PDF?

Yes. XML Viewer can export XML to PDF with full XML or current expanded view, black-and-white or color output, page numbers, and line number options. Free PDF export may be limited to the first 200 lines; Pro removes the line limit and unlocks advanced PDF options.

Can XML Viewer save or share formatted XML?

Yes. XML Viewer can save the formatted XML through Android's save picker and share formatted XML through Android's share sheet.

Can I export just one XML node?

Yes, with Pro. Long-press a node and choose Export as XML to save that node as a standalone XML file.

Does XML Viewer validate XML against an XSD or schema?

No. XML Viewer is for viewing, searching, and exporting XML. It does not perform XSD validation, schema analysis, XML editing, auto-repair, or schema generation.

What happens if my XML is invalid?

XML Viewer shows a friendly error instead of a raw technical message. Free users see a simple "Unable to open XML file" style message. Pro users get more specific XML error details when available, including line and column information.

Can I customize the viewer?

Yes. Settings include theme mode, color theme, indentation size, font size, long-line wrapping, line numbers, and large file mode for Pro users.

What Android versions does XML Viewer support?

XML Viewer supports Android 8.0 and newer.

Why does XML Viewer ask for camera permission?

Camera permission is used for QR scanning only. You can open XML files, paste XML, and load XML from URLs without using the camera.
