9 Best Free XML Syntax Checker Software For Windows

Here is a list of best free XML syntax checker software for Windows. These software analyze the XML code and find syntax error if there is any. Not just finding errors, but these also specify the type of errors and the exact line containing an error. Some of these software also specify the exact column of error to pinpoint the error. Apart from writing the code, you can also add XML files containing XML code to these XML syntax checkers to quickly find the syntax error. The process of checking XML syntax error is pretty simple in all software. In some software, you need to activate the syntax checking feature, while other software automatically show error as soon as they detect it. Most of these software are basically XML editors, hence they also let you edit XML files.

Apart from checking XML syntax, these software can also be used to validate XML documents. Plus, various handy features like a spelling checker, word counter, schema converter, code debugger, etc. are also present in many software. Along with XML file, many software support files of various formats like HTML, XML, DTD, XSD, PDF, etc. After checking and fixing XML syntax error, you can save the XML code again in the XML format or in other supported formats.

Besides this, you can also add an existing XML file and immediately check its syntax as well. After analyzing the syntax, this software shows error type and line of error, if found any. In case of no error, a success message is shown to indicate that the syntax has no error.

After the completion of syntax verification, you get an error message in case of any detected error along with the line of the error, so you can quickly find and correct it. If no error is found by it, then it shows “your document is well-formed” message.
