Free Online SOAP Formatter
SOAP Formatter takes raw or minified SOAP XML and rewrites it with clean, readable indentation so you can inspect envelope structure, namespaces, and headers at a glance. You get five specialized tools in one workspace: a formatter for prettifying envelopes, a minifier for compacting strings, a validator for structural checks, a converter for JSON output, and an extractor for isolating specific sections. Just paste your SOAP XML, upload a file, or drag and drop it onto the page. Every operation runs locally in your browser, ensuring your SOAP messages stay private and never leave your device.
SOAP Formatter
Get clean, readable SOAP XML with custom indentation while keeping all namespaces and declarations exactly as they were.
SOAP Minifier
Compress SOAP envelopes for smaller API payloads by removing all unnecessary whitespace and comments from the XML.
SOAP Validator
Check your SOAP envelope structure, identify the version, and confirm that Header and Body elements are correctly placed.
SOAP to JSON
Turn SOAP XML into structured JSON where attributes and repeated elements are converted into a clean, usable object format.
SOAP Extractor
Break down your SOAP envelope into Header, Body, and Fault sections, each displayed in its own formatted panel for isolation.
Online SOAP Formatter with File Upload and Indentation Options
Debugging SOAP messages is much easier with readable formatting. Paste a raw envelope into the editor, pick your preferred indent size, and click Format to see the prettified results instantly. Indentation is applied consistently while preserving all namespace declarations, processing instructions, and CDATA sections so every nested element is easy to follow. You can also upload .xml, .soap, or .wsdl files directly or just drag them onto the workspace.
Configurable Indentation and XML Declaration Handling
Select 2-space, 4-space, or tab-based indentation from the dropdown menu to match your coding style. If your message includes an XML declaration, it stays right on the first line where it belongs. All namespace prefixes, attribute values, and text content remain untouched during the process.
Drag and Drop SOAP Files
Drag any XML or SOAP file onto the workspace to load it instantly. The contents appear in the editor ready for formatting, validation, or conversion. You won't run into file size limits because everything is processed locally within your browser's memory.
Validate, Convert, and Extract SOAP Envelope Parts
Beyond formatting, you may need to verify that a SOAP message is structurally sound before sending it to an endpoint. Use the SOAP Validator to check the root Envelope, identify the version (1.1 or 1.2), and confirm that Body elements are present. All declared namespaces are listed clearly so you can spot missing or incorrect URIs at a glance.
Convert SOAP XML to JSON
Transform your entire SOAP envelope into a structured JSON object for easier processing in modern applications. Element names become keys, attributes move to an @attributes object, and repeated tags are automatically grouped into arrays. This is perfect for working with SOAP data in JavaScript, Python, or other languages where JSON is preferred.
Extract Header, Body, and Fault Sections
Isolate the Header, Body, and Fault sections into individual formatted XML blocks with the built-in extractor. Each panel includes its own copy button so you can grab exactly what you need for debugging. If a Fault element is found, it is highlighted in a dedicated panel to help you identify errors immediately.
Free SOAP Formatter for Developers and API Testers
Whether you are debugging service responses or preparing requests for testing, you get instant formatting and analysis without installing any software. Every feature is available right away with no signups, accounts, or usage limits. Your exports come in their original format without any watermarks. Since nothing is stored on a server, your SOAP messages disappear when you close the tab, making this a secure choice for handling sensitive data.
No Installation, No Signup, No Limits
Access the entire suite of SOAP tools immediately without hitting paywalls or premium restrictions. There are no limits on file sizes or the number of operations you can perform. Your session data is cleared from memory as soon as the tab is closed, keeping your privacy intact by design.
Client-Side Processing for Sensitive SOAP Messages
All processing happens right in your browser using standard web APIs. No SOAP envelopes, tokens, or payloads ever leave your computer or travel across the network. This local approach is ideal for handling production messages that contain credentials or other sensitive business information.
