The document describes the file format for saving spreadsheet data. It includes details on how cell values, formulas, formatting, and other metadata are encoded in a line-based text format. Key elements include cell coordinates, value types (numeric, text), formulas, formatting codes, borders, colors, and default styles at the sheet level. The format is designed to encode all information needed to reconstruct the spreadsheet for viewing or editing.
