Set Attribute - lifelike/countersheetsextension GitHub Wiki
It is possible to set any SVG Attribute of any object in the template to a new value given in the CSV data. The syntax for doing this is to put id[attribute] in the header for a column, where id must be the id (see Object Properties) for an object in the template and attribute must be the name of an attribute of that object.
For instance use the XML Editor (in the Edit menu) in Inkscape to see that attributes an object has and what values it receives when editing it in Inkscape. It can be possible this way to find out what values are wanted and then copy them into a spreadsheet to give it to different values.
A special case that is probably wanted most often is to edit the style attribute of an object. The style usually consists of many different parts and setting the entire style attribute is likely to produce a very cluttered spreadsheet. Therefore there is also a special way to Set Style that will only affect a single part of the style attribute without affecting the other parts (for instance to only give counters different fill styles when all other parts of the style shall remain as in the template).
