Question details

- Product
- Excel for the Web
- Device & OS
- not provided
- Scenario
- Creating advanced data visualizations and attempting to define specific positive and negative error values for a chart online.
- Observed behavior
- The custom error bar options are missing entirely from the Excel for the web interface, despite being available in the desktop version.
Before proceeding, ensure you have a full desktop spreadsheet program installed, as this specific charting feature is intentionally excluded from browser-based spreadsheet applications.
Open the Workbook in the Desktop Version of Excel
Since custom error bars are unsupported in the web application, transitioning your active session to the desktop app is the fastest way to add them.
Excel for the web is designed for lightweight editing and does not support complex chart elements. However, any custom error bars added via the desktop application will render correctly when the file is viewed later in the web browser.
Look at the top ribbon menu in your Excel for the web interface and click on the 'Editing' or 'Viewing' dropdown button.
Select 'Open in Desktop App' from the dropdown menu. Confirm any browser prompts to allow Microsoft Excel to open.
In the desktop app, click on your chart, select the plus icon (+) for 'Chart Elements', hover over 'Error Bars', click the arrow, and choose 'More Options' to define your custom values.

Vote for the Feature Request on Microsoft Feedback
If your organization restricts desktop app usage and relies solely on web tools, you can formally request that Microsoft add this feature to Excel online.
