Which Files Can I Preview, and Why Won't a Document Open?

For Sponsors and InvestorsBy Syndelo

Which file types open in the built-in preview and what to do when one does not.

Click a document's name in the documents list to open a preview. If a file type cannot be previewed, download it instead.

Steps

  1. Open Documents (investors: Documents in the portal).
  2. Click the document name to open the preview.
  3. To save a copy, click Download.

File types that preview

  • PDF: shown page by page.
  • Images: PNG, JPG, GIF, WebP, AVIF, and BMP.
  • Video: MP4, WebM, MOV, and OGV. Audio: MP3, WAV, OGG, and M4A.
  • Text: TXT, CSV, JSON, MD, CSS, HTML, and XML, shown as plain text.
  • Word (.docx): text only. Formatting, tables, and images may not appear.

Other types, such as Excel or PowerPoint, cannot be previewed. Download them.

Why a preview fails

  • "Unable to load this document" means the file could not be fetched. Reopen the preview or download it.
  • "This Word document cannot be previewed" means the file is damaged or not a standard .docx. Download it to view it.
  • A file marked Permanently deleted cannot be opened or downloaded.
  • Investors see only files shared with their investing accounts or investments.

Good to know

Syndelo is in preview. eSign and investor payments require live provider setup; a demo or sandbox action does not complete a live transaction. Confirm availability for your workspace before relying on either.
