Testimonials & Reviews

"We have purchased the license for XmlSplit. The program creates exactly the xml files we need, including the XmlDeclaration. A file of 2.5 GB was processed without any problems - and in a very reasonable time."

Johan Van Loon, TMB Bookshop, Belgium.

"Your editor does an excellent job with files that my primary XML editor will not load in a reasonable time. I was viewing files having 700,000-800,000 nodes. XMLMax opened and displayed these files quickly and efficiently."

Ken White, LegalXtraNet, San Antonio, TX

From a 2009 Review of XMLMax:

"Recently I came across a tool that was very helpful in the review of large XML documents…..REALLY large xml documents…..Hundreds of megabytes and more! In the years I’ve been working with XML, every so often I come across a document that I can’t read, can’t process, or can’t otherwise easily research for a data integration application. The tools I usually employ either hit errors or take forever to open while parsing thru thousands upon thousands of elements and attributes. "
