Ranges

Ranges use A1 notation and are the main surface for reading and writing cells.

const sheet = workbook.worksheets.add("Sheet1");

sheet.getRange("A1:C1").values = [["Month", "Bookings", "ARR"]];
sheet.getRange("A2:C4").values = [
  ["Jan", 120000, 1440000],
  ["Feb", 135000, 1620000],
  ["Mar", 142000, 1704000],
];

sheet.getRange("E2").formulas = [["=SUM(C2:C4)"]];
workbook.recalculate();

Notes

• Use range.values for literal values.
• Use range.formulas for Excel-style formulas.
• Call workbook.recalculate() before reading formula-driven range.values.
• Apply formatting through range.format when the sheet needs borders, fills, fonts, or number formats.

Addressing

• Single cell: "B3"
• Rectangle: "A1:C10"
• Entire row or column ranges are best used sparingly unless the user explicitly wants them.
