XML Creator

Free Online XML Creator

XML Creator helps you build well-formed XML documents from scratch without writing a single angle bracket by hand. We combined five XML utilities into one workspace so you can visually construct elements, convert JSON or CSV into XML, start from ready-made templates, and generate XSD schemas for validation. Paste your data, upload a file, or fill in the form fields and get clean, properly indented XML in seconds. Your data never leaves your device because everything runs in the browser.

Online XML Creator with Visual Form Builder

Writing XML by hand is tedious and error-prone. Missing a closing tag, forgetting to escape an ampersand, or mismatching element names can break an entire document. Our visual form builder eliminates these problems by letting you define elements through simple input fields. You type the element name, add text content, attach attributes as key-value pairs, and nest children up to three levels deep. The generated XML updates instantly in the code editor beside the form so you always see exactly what you are producing.

How the Form Builder Works

Start by naming your root element at the top of the builder panel. Toggle the XML declaration checkbox if you need the standard processing instruction. Click Add Element to create a top-level child, then fill in its name and optional text content. Use the Attr button to add attributes and the Child button to nest elements inside. Each nesting level gets a colored left border so you can see hierarchy at a glance. When you are done, copy the output or download it as an .xml file.

Upload Files to Pre-populate

If you already have data in another format, you can upload it directly. The JSON to XML converter accepts .json files, the CSV to XML converter accepts .csv files, and the Schema Generator and Templates tools accept .xml files. Drag and drop works too. Because everything runs locally in your browser, there is no file size limit and no risk of exposing sensitive data to external servers.

Convert JSON and CSV to XML

Switching between data formats is a common task for developers working with APIs, databases, and legacy systems. Our JSON to XML converter walks JSON objects recursively, turning keys into element names and arrays into repeated elements. A single-root JSON object keeps its key as the root element, while multi-key objects get wrapped in a generic root. The result is clean, indented XML with an XML declaration ready for use.

The CSV to XML converter reads the first row as column headers and uses them as element names for each data row. Every row becomes a record element with children matching those headers. Special characters in cell values are escaped automatically so you never produce invalid XML from raw spreadsheet exports. Paste data directly or upload a .csv file.

Start Fast with XML Templates

When you need a quick starting point for a standard XML format, the Templates tool offers six commonly used structures: RSS feeds for blog syndication, sitemaps for search engine indexing, SOAP envelopes for web service calls, Android layout definitions, Maven POM files for Java projects, and Spring configuration for dependency injection. Select a template, edit it in the code editor, and download the finished document.

Generate XSD Schemas from Existing XML

If you have an XML document and need a schema to validate it, the Schema Generator inspects your document structure and produces a basic XSD. It detects five data types in text content: integers, decimals, booleans, dates in YYYY-MM-DD format, and plain strings. Repeated elements under the same parent are marked with maxOccurs unbounded. Attributes are declared as xs:string. The output gives you a solid starting point that you can refine as needed.

Your Data Stays on Your Device

We process everything in your browser using DOMParser, JavaScript string operations, and local state management. Your XML, JSON, and CSV data never touches our servers. That means you can safely create XML documents containing database credentials, internal API endpoints, configuration secrets, and customer information without any privacy concerns. No server communication, no cookies, no signup required.
