Smartsheet Dark Mode

Smartsheet has no native dark mode. The interface is built around a bright white and light grey palette across sheets, reports, dashboards, and tool panels. For users who work long hours in Smartsheet or in low-light environments, the constant bright background causes eye strain that no Smartsheet setting can address.

Without Grid Tools

The daily workaround

Bright white interface all day
Smartsheet's default light theme is fixed — there is no appearance setting or theme switcher anywhere in the product.
Eye strain in low-light environments
Working in a dark room or at night with a full-brightness Smartsheet tab is fatiguing, with no way to reduce glare from within the app.
OS dark mode has no effect
Enabling dark mode at the operating system or browser level does not change the Smartsheet UI, which ignores the system preference.
Third-party workarounds break regularly
Browser CSS injection extensions can apply dark colours to Smartsheet, but they are unstyled, break layouts, and stop working after Smartsheet updates.

With Grid Tools

How Grid Tools handles it

Purpose-built dark theme for Smartsheet
Grid Tools applies a dark colour scheme designed specifically for the Smartsheet interface, not a generic CSS inversion.

Dark mode applies across sheets, reports, the toolbar, right-hand panels, and dialog boxes for a consistent low-light experience.
Specific tool areas covered too
Grid Tools extends dark mode to additional Smartsheet areas including Generate Document, Control Center, WorkApps, and Bridge.
Toggle on or off at any time
Dark mode is controlled through the Grid Tools extension panel and can be turned on or off without a page reload.
