How do I register custom styles in Cloud Reporting?
In Bold Reports® Cloud, you create a custom styles file and register it in a single step by uploading it to the server with the File Upload feature.
How to create a custom styles JSON file
A custom styles file is a JSON file named {name of file}.json that defines the required CSS styles. Use the following format:
"table header": {
"font-family": "arial",
"font-size": "13.333333333333334px",
"font-weight": "bold",
"background-color": "#6495ED",
"border-bottom-color": "navy",
"border-right-color": "gray",
"border-left-color": "gray",
"border-right-width": "1.333px",
"border-left-width": "1.333px",
"border-top-width": "2px",
"border-bottom-width": "2px",
"border-bottom-style": "double",
"border-top-color": "navy"
},
"header": {
"background-color": "#6495ED",
"font-family": "arial",
"font-size": "0.16666979166666665in",
"font-style": "normal",
"font-weight": "bold",
"color": "white"
}How to register custom styles with file upload
You register custom styles by uploading the JSON file with File Upload and setting the Name field to custom_style.
To register external custom styles in Cloud Reporting, admins or the uploading user can create and manage a custom styles file in a straightforward way. The uploaded custom styles file serves as a common styling reference for all users within the site, allowing them to apply their own formatting preferences. To configure the custom styles via file upload, follow these steps:
-
Refer to the File Upload section in Bold Reports® Report Server and upload your custom styles JSON file.

Note: In the Upload File dialog, the Name field must be set to
custom_style -
Once the file is uploaded, another file with the same name [custom_style] cannot be uploaded again.
-
To modify the styles in an existing uploaded file, you must re-upload it. Only the user who originally uploaded the file or an administrator can do this.
Note: If a report is open in the Designer tab, reload it after uploading the file.
Frequently asked questions
What name must the custom styles file have when I upload it?
Set the Name field to custom_style in the Upload File dialog. The server does not accept a second file with the same name.
How do I apply a registered custom style to a report?
In the Bold Reports® designer, open the Properties panel. Under Miscellaneous in Report Properties, choose a style key from the Custom Style dropdown. See Configure custom styles into report items.
Why don’t my new styles appear in the designer?
If a report is already open in the Designer tab, reload it after you upload the custom styles file.
