What is CSE HTML Validator Professional?
CSE HTML Validator Professional helps web developers find problems in HTML, XHTML and CSS. Its validation tools combine code checking with spelling, link and accessibility checks, so you can review several kinds of website issues in one desktop application. Validation messages can be changed or disabled to focus on the issues relevant to your work. The source-hosted author review says document validation runs locally rather than uploading your documents.
This is the Professional trial, not the Standard edition described separately as free for personal, non-commercial use. The linked Windows EXE is a FileEagle mirror listed as CSS HTML Validator Professional 26.01; it is not hosted by the publisher. Only its HTTP headers were checked: the installer was not downloaded, installed or tested.
The screenshot shows the application's Windows Editor Options dialog on the Spell Checking page. It is a source-gallery illustration, not a verified capture of version 26.01. Exact supported Windows versions and processor architecture were not independently established.
What it offers
- Check HTML, XHTML and CSS for coding problems.
- Review spelling, links and accessibility alongside markup checks.
- Change or disable validation messages to suit the issues you want to investigate.
- Validate documents locally, according to the author review hosted on the source page.
Good to know
- The Professional edition is offered as a trial; the source's free personal-use statement applies to Standard, not Professional.
- The download is a third-party mirror. Header verification does not establish installer authenticity or runtime compatibility.
- The gallery screenshot does not establish the interface of version 26.01, and exact Windows-version and architecture requirements remain unverified.
