The attachment field allows you to store any type of file within a record. Depending on the file type, Airtable will generate a small thumbnail preview of the document, and/or a full-screen document preview. This article covers the different file types that support previews.
Thumbnail previews
Thumbnails appear as a small preview of the document file, which will adjust based on row height. Thumbnail previews are generated for the following file types:
-
Image and design files (.png, .jpg, .gif, .svg, .psd, and .tiff file formats)
-
Word documents (.doc and .docx)
-
Excel files (.xls, .xlsx, and .csv)
-
Text files (.txt)
-
PDF documents (.pdf)
-
Powerpoint presentations without embedded videos (.ppt and .pptx)
Full-screen document previews
Full-screen attachment previews provide a way to view the supported file types (below), but not edit them directly in Airtable. We support viewing the following file types:
-
Image and design files (.png, .jpg, gif, .psd, and .tiff file formats)
-
Video files (HTML5 format, which is browser dependent)
-
Word documents (.doc and .docx)
-
Excel files (.xls, .xlsx, and .csv)
-
Text files (.txt)
-
PDF documents (.pdf)
-
Powerpoint presentations without embedded videos (.ppt and .pptx)
-
XML data (.xml)
Limitations for attachment previews
-
Excel preview does not follow time information in the original file. When previewing Excel documents, the time-related functions (for example, TODAY() or TIME()) do not display accurately. This is because Excel date/time functions are dynamic, while the previewed document is static. The document preview obtains and displays the date the file was previewed. A static version of the time/date is displays in the previewed document, based on the time the preview was generated.
-
You cannot preview password-protected files.
-
Hyperlinks do not work in PowerPoint files in previews on either the Web, m.box, or mobile applications.
-
Videos embedded in Powerpoint files do not work in Preview.
-

-
Small-sized files (1-byte) cannot be previewed on m.box.com
