XLS Background Colorizer

The XLS Background Colorizer node changes the background color and/or pattern fill for selected cells. The color information is statically defined. Consider using the XLS Conditional Formatter node if you want your spreadsheet application to color the cell background according to its numeric value.

This node's standard mode of operation is to receive the selection of cells to modify via tags in the provided XLS Control Table and the formatting instructions via the node dialog. However, it also provides a direct mode in which the XLS Control Table does not hold tags, but the desired color values directly (in RGB format, e.g. red either as #FF000 or 255/0/0) or missing values for cells not intended to be colorized. Note that the xlsx file format allows a maximum of 64,000 distinct styles per workbook only. Hence, even using a small fraction of the 16.8 million possible RGB colors can easily exhaust this quota.

This node defines a formatting instruction only which needs to be written to an xlsx file via the XLS Formatter (apply) node subsequently.

Options

Control table style: Choose the control table style: Either use a tag to define your background color (standard tags) or use RGB color codes in your control table (e.g. 255/0/255 or #FF00FF).
Applies to tag (single tag only): Tag in your input table for which the formatting of this node should be applied to.
Change background color: If you want to change the background color you can enable it here.
Background color: Choose a color in hex format with optional alpha channel.

Change pattern color: If you want to change the pattern fill color you can enable it here.
Pattern color: Choose a color in hex format with optional alpha channel.
