Question

Is there a built-in way to use the ["key"] indexer directly on Dictionary<string, object> inside {{ ... }} expressions in ClosedXML.Report templates?

If not, are there recommended best practices for working with nested dictionaries (e.g. Dictionary<string, object> containing other dictionaries) in templates?

Sample data structure

var items = new List<Dictionary<string, object>>
{
    new Dictionary<string, object>
    {
        ["id"] = 1,
        ["nodes"] = new Dictionary<string, object>
        {
            ["dynamic_node"] = new Dictionary<string, object>
            {
                ["availability"] = "Available"
            }
        }
    }
};
