Formatting Behavior
Most formatting properties support a Do not change option.
When selected, the corresponding formatting attribute remains unchanged.
This allows workflows to update only specific formatting properties while preserving existing cell formatting.
Linux Font Dependencies (Ubuntu)
When workflows run on Linux, font-specific formatting depends on fonts installed on the execution host. If a configured font is unavailable, Linux applies a fallback font and the output may not match the expected style.
Use the following commands on Ubuntu to install common fonts required by spreadsheet templates:
sudo apt update
sudo apt install -y fontconfig fonts-dejavu fonts-liberation fonts-noto-core
sudo apt install -y ttf-mscorefonts-installer
Refresh the font cache after installation:
sudo fc-cache -f -v
Verify that required fonts are available:
fc-list | sort
To verify specific font families:
fc-list | rg -i "calibri|arial|times new roman|dejavu|liberation"
Troubleshooting
- If formatted output does not match expected results, verify that the configured font family is installed with the exact family name used in the workbook.
- If the
ttf-mscorefonts-installerpackage is unavailable, use equivalent open-source fonts such as Liberation fonts and align workbook templates accordingly. - If fonts were installed recently but are still not applied, re-run
fc-cache -f -vand restart the workflow execution service. - In containerized deployments, fonts must be installed inside the container image. Installing fonts only on the host does not make them available within containers.
