Is there a way to change the color of a line shape in an Office.js Excel add in?

Question

I have tried the shape.fill.setSolidColor("color"); method as well as fill.setForegroundColor = 'color'; property. Neither of these seems to work and at times throw errors. Can a line shape be changed from its default blue color in excel add-ins? Much appreciated.

Welcome to Office JS world, Yes, the line shape color can be changed by Shape.lineFormat API. You may try the following sample code in the script lab

async function addStraightLine() {
  await Excel.run(async (context) => {
    const shapes = context.workbook.worksheets.getItem("Shapes").shapes;
    const line = shapes.addLine(200, 50, 300, 150, Excel.ConnectorType.straight);
    line.lineFormat.color = "red";
    line.name = "StraightLine";
    await context.sync();
  });
}
