Deprecation of Legacy Worksheets and Dashboards¶
Snowflake is deprecating two legacy surfaces in Snowsight: Legacy Worksheets and Legacy Dashboards.
- Legacy Worksheets are replaced by Workspaces, the modern SQL editing experience that supports file-and-folder organization, sharing, and Git integration.
- Legacy Dashboards are retired, with migration paths to Streamlit apps or third-party BI tools.
Important
Starting June 22, 2026, Snowflake will begin rolling out the removal of Legacy Worksheets and Legacy Dashboards from Snowsight. The rollout starts gradually on June 22 and completes over a few weeks.
Migrate your dashboards before this date. For Legacy Worksheets, migration is optional — existing worksheets remain accessible from Workspaces after the Legacy Worksheets UI is removed. See Bulk migration tool.
Note
Reader accounts do not yet support Workspaces and are exempt from this deprecation of Legacy Worksheets and Legacy Dashboards. Snowflake will publish a separate notice with the deprecation timeline for reader accounts after Workspaces is fully available for reader accounts.
Timeline¶
| Date | Worksheets | Dashboards |
|---|---|---|
| April 20, 2026 | Workspaces becomes universal and the default editor for all accounts. Workspaces can no longer be disabled. Account administrators can still temporarily revert to Legacy Worksheets as the default editor until June 22. Self-service worksheet migration tooling available. | Creation of new dashboards is disabled across all accounts. |
| June 22, 2026 | Rollout to remove the Legacy Worksheets standalone UI from Snowsight begins on June 22 and completes over a few weeks. Existing worksheets remain accessible from the Legacy Worksheets section in the Workspaces sidebar. Use the bulk migration tool to optionally convert worksheets to Workspaces files. | Rollout to remove Legacy Dashboards from Snowsight begins on June 22 and completes over a few weeks. Dashboards are no longer accessible after removal from your account. |
Legacy Worksheets¶
Legacy Worksheets are replaced by Workspaces, a modern SQL editing experience that supports file-and-folder organization, sharing, and Git integration. Most accounts are already using Workspaces as their default editor.
For the previous behavior change that defaulted accounts to Workspaces, see Defaulting accounts from Worksheets to Workspaces.
- Before the change:
Legacy Worksheets is available as a SQL editing experience in Snowsight. Account administrators and individual users can revert from Workspaces to Legacy Worksheets as the default editor using the
USE_WORKSPACES_FOR_SQLparameter or the corresponding controls in the Snowsight settings.- After the change:
The Legacy Worksheets standalone UI is removed from Snowsight.
-
April 20, 2026: Workspaces can no longer be disabled. The feature flag used to disable Workspaces (documented in Disable Workspaces) is ignored. All remaining accounts are defaulted to Workspaces as the default SQL editor.
Account administrators can still temporarily revert the default editor to Legacy Worksheets using the
USE_WORKSPACES_FOR_SQLparameter:This revert capability is available until June 22, 2026.
-
June 22, 2026: Rollout to remove the Legacy Worksheets standalone UI begins and completes over a few weeks. Entry points to the Legacy Worksheets UI are removed from Snowsight. Setting
USE_WORKSPACES_FOR_SQLto'never'is no longer supported. Existing worksheets remain accessible from the Legacy Worksheets section in the Workspaces sidebar.
-
Bulk migration tool¶
A self-service bulk migration tool is available to convert Legacy Worksheets to Workspaces files. In Workspaces, open the Legacy Worksheets section in the sidebar; the tool is accessible from the banner above that section.
Note
Using the bulk migration tool is not required before the deprecation date. This deprecation removes the Legacy Worksheets standalone UI — not your ability to access and use existing worksheets from Workspaces. After the Legacy Worksheets UI is removed, your worksheets remain accessible from the Legacy Worksheets section in the Workspaces sidebar. The bulk migration tool remains available so you can migrate at your own pace.
Python worksheets¶
Unlike SQL worksheets, Legacy Python worksheets must be migrated to remain executable after the Legacy Worksheets UI is removed.
The bulk migration tool converts Python worksheets to Workspaces files named worksheet_name.py.sql.
These files contain the same stored procedure logic that Legacy Python worksheets use today, so
migrated Python worksheets remain executable in Workspaces without relying on native Python support in
Workspaces. Snowflake recommends adopting native Python support in Workspaces over time, but it is not
required to continue running migrated Legacy Python worksheets.
Shared worksheets¶
Worksheets previously shared with other users remain accessible to all shared users from the Legacy Worksheets section in the Workspaces sidebar.
When you use the bulk migration tool to convert worksheets to Workspaces files, a copy is created for each user who had access. The shared status is not preserved after migration.
For ongoing collaboration, use shared workspaces, which allow teams to collaborate in dedicated spaces with role-based access control and a wiki-style draft and publish model. Shared workspaces are the recommended replacement for shared worksheets.
Legacy Dashboards¶
Snowsight Dashboards are retired. Snowflake provides a Dashboard-to-Streamlit conversion tool to migrate existing dashboards to Streamlit apps running natively on Snowflake. You can also migrate to any third-party BI or visualization tool.
- Before the change:
Snowsight Dashboards are available in Snowsight for creating and viewing dashboards.
- After the change:
Snowsight Dashboards are removed from Snowsight.
- April 20, 2026: Creation of new dashboards is disabled across all accounts. Any action that would create a new dashboard is blocked.
- June 22, 2026: Rollout to remove dashboards from Snowsight begins and completes over a few weeks. Existing dashboards are no longer accessible after removal from your account.
Dashboard migration options¶
- Streamlit: Open any existing dashboard and select Generate Streamlit app to convert it to a Streamlit app running natively on Snowflake.
- Third-party BI tools: Migrate to any BI or visualization tool of your choice.
Important
Migrate your dashboards before June 22, 2026. After dashboards are removed from your account, they are no longer accessible.
Actions required¶
For Legacy Worksheets¶
- Verify Workspaces access: Ensure your users can access Workspaces and that it functions as expected for your workflows.
- Review existing worksheets: Open the Legacy Worksheets section in the Workspaces sidebar to verify that your worksheets are accessible.
- Migrate worksheets to Workspaces files (optional): Use the bulk migration tool or drag worksheets into your workspace to convert them to Workspaces files. Migration is not required before the deprecation date.
- Update automation or bookmarks: If you have bookmarks, automation, or documentation that references Legacy Worksheets URLs or entry points, update them to use Workspaces.
For Snowsight Dashboards¶
- Migrate dashboards before June 22, 2026: After dashboards are removed from your account, they are no longer accessible.
- Use the conversion tool: Open any dashboard and select Generate Streamlit app to convert it to a Streamlit app.
- Consider alternative tools such as Snowflake CoWork: You can also migrate to third-party BI or visualization tools.
Additional notes¶
- Legacy notebooks: Legacy Notebooks are not affected by this deprecation and remain functional. Snowflake will address Legacy Notebooks through a separate BCR.
- Temporary revert controls: Between April 20 and June 22, 2026, account administrators can
temporarily revert the default editor to Legacy Worksheets using the
USE_WORKSPACES_FOR_SQLparameter. Individual users can also revert their own default. These controls are removed on June 22, 2026. For details on these controls, see Defaulting accounts from Worksheets to Workspaces.
