Configure file columns on input tables (Beta)

Add file columns to upload images, documents, and videos directly to input tables or to support file upload in forms. File columns can accept the following file types, which can be restricted at the column level:

• Images: JPEG/JPG, PNG, GIF, TIFF, BMP, WebP, SVG
• Documents: PDF, CSV, DOC/DOCX, XLS, XLSX, Pages, Numbers, Keynote, JSON, Text file, XML
• Videos: MP4, MOV, AVI, MKV, WebM, M4V

You can also limit the number of files per cell and set a maximum size per file.

This document explains how to add a file column to an input table and configure upload restrictions. For information about using file columns, see Add or edit input table data.

Requirements

The ability to add a file column to an existing input table and configure upload restrictions requires the following:

• Your organization must have an existing storage integration for file uploads. See Configure a storage integration for file uploads.

• You must be assigned an account type with the Create input tables and Create, edit, and publish workbooks permissions enabled.

• You must be the workbook owner or be granted Can edit workbook permission.

For information about the requirements to create new input tables, see Create new input tables.

Add a file column to an input table

Add a file column that allows users to upload one or more files to an individual row in an input table.

1. Open the draft version of a workbook and locate the input table you want to edit.

2. In the input table you want to edit, click the plus () icon at the end of the column header, then select File from the dropdown. Sigma adds a file column to the input table.

Configure file upload restrictions

Configure file restrictions for security, compliance, and performance purposes. You can add file upload validation at the column level to restrict the following:

• Number of files users can upload to a single cell

• Accepted file types

• Maximum size per file

By default, a file column allows multiple files per cell (without restriction), accepts all supported file types, and has a 200 MB maximum file size.

1. In the file column header, click the down arrow () to open the column menu, then select Data validation.

2. In the Data validation modal, configure the following options, then click Save:

   Allow multiple files	To allow users to upload multiple files simultaneously, select the checkbox. To limit each upload to a single file, clear the checkbox.
   Restrict number of files	When you allow multiple files per upload, you can set a maximum number of files users can upload simultaneously. To limit the number of files, select the Restrict number of files checkbox, then enter the file limit in the Max number field (displayed when the checkbox is selected).
   Accepted file types	Select the file types users are allowed to upload. A checkmark displays next to accepted file types, unless all are accepted (then no checkmarks display).
   Max size	Enter the maximum size allowed per file.
