HTML Editor

Description

Visual and source-code editor for creating HTML documents stored as Cloud services, with preview and multi-format export.

Use cases

  • Write HTML content for email, web, or documentation.
  • Switch between visual editing and source code.
  • Prepare formatted tables, links, lists, and images.
  • Export a copy as HTML, text, or a document.

How to create the service

Open Cloud > New item, select HTML Editor, enter a name and folder, and create the document. An uploaded HTML file can be opened with this application when registered as compatible.

Interface and controls

The visual toolbar includes text formatting, lists, links, tables, images, alignment, undo, and redo. Code mode exposes HTML source. Preview renders sanitized content in the browser. Header actions save, open versions, and export.

Full workflow

  1. Create the service and write in visual or code mode.
  2. Structure content with headings, paragraphs, lists, and tables.
  3. Add links and accessible image resources.
  4. Review source code and remove unnecessary markup.
  5. Check preview and correct styles.
  6. Save a version and export the required format.

Supported files or data

The service handles HTML content and compatible HTML/HTM files. Images use URLs or Cloud resources where selection is available. Scripts, event attributes, and unsafe elements may be removed or prevented from running.

Configuration options

Options include text styles, size, color, highlighting, alignment, links, lists, tables, images, source code, history, and preview. Export offers format and destination-specific conversion settings where available.

Output and export formats

HTML is the editable format. Available output can include HTML, TXT, JSON, Word HTML, DOCX, PDF, or EML. TXT removes visual structure, while DOCX and PDF may interpret CSS differently from a browser.

Saving, downloading and sharing

Saving retains editable HTML and versions. Download or export creates a copy without replacing the project. Share from Cloud and use Users for account access. Avoid private resource URLs that recipients cannot open.

Limits and technical requirements

Content is sanitized and is not a JavaScript application runtime. DOCX or PDF export depends on converters and can ignore advanced CSS, remote fonts, or responsive layout. Service size and storage limits apply.

Common errors

  • Code disappears after saving: security sanitization probably removed it.
  • Preview differs: validate HTML, supported CSS, and resource URLs.
  • An image does not load: check URL, Cloud permissions, and HTTP/HTTPS mixed content.
  • PDF or DOCX layout changes: simplify CSS and use installed fonts.

Privacy and data processing

Do not place keys, tokens, or personal data in public HTML. Sanitization reduces XSS risks, but authors remain responsible for links, remote images, and embedded content. Review trackers and third-party resources before sharing.

Frequently asked questions

  • Can JavaScript run? It should not be considered supported; active content may be blocked or removed.
  • Is source code retained? Yes, after sanitization applied on save.
  • Is this a Landing? No; HTML Editor creates a document, while Landing adds publishing, sections, forms, and statistics.
