get_range_values
Extract specific data ranges from Excel sheets by specifying file path, sheet name, and range (e.g., A1:C10). Streamlines data retrieval for analysis or processing through the Excel MCP Server.

Implementation Reference
- src/index.ts:307-342 (handler)Core handler function that validates the range, loads the Excel workbook and worksheet, parses the range boundaries, iterates over the cells to collect values into a 2D array, and returns a formatted JSON string of the values.async function getRangeValues(filePath: string, sheetName: string, range: string): Promise<string> { try { validateRangeAddress(range); const workbook = await loadWorkbook(filePath); const worksheet = workbook.getWorksheet(sheetName); if (!worksheet) { throw new Error(`ワークシート '${sheetName}' が見つかりません。利用可能なシート: ${getSheetNames(workbook)}`); } const rangeCells = worksheet.getCell(range); const values: any[][] = []; // 指定範囲のデータを取得する正しい実装 const [startCell, endCell] = range.split(':'); const startCellObj = worksheet.getCell(startCell); const endCellObj = worksheet.getCell(endCell); const startRow = Number(startCellObj.row); const startCol = Number(startCellObj.col); const endRow = Number(endCellObj.row); const endCol = Number(endCellObj.col); for (let row = startRow; row <= endRow; row++) { const rowValues: any[] = []; for (let col = startCol; col <= endCol; col++) { rowValues.push(worksheet.getCell(row, col).value); } values.push(rowValues); } return `範囲 ${range} の値:\n${JSON.stringify(values, null, 2)}`; } catch (error) { throw new McpError(ErrorCode.InternalError, `範囲値取得エラー: ${error}`); } }
- src/index.ts:50-54 (schema)Zod schema defining the input parameters for the get_range_values tool: filePath (absolute path to Excel file), sheetName (worksheet name), range (cell range like A1:C3).const GetRangeValuesSchema = z.object({ filePath: z.string().describe("対象のExcelファイルの絶対パス"), sheetName: z.string().describe("対象のワークシート名"), range: z.string().describe("取得する範囲。A1:C3形式で指定（例: A1:C10, B2:D5）"), });
- src/index.ts:551-554 (registration)Tool registration in the toolImplementations map: parses input arguments using the schema and delegates to the core getRangeValues handler function.get_range_values: async (args: any) => { const { filePath, sheetName, range } = GetRangeValuesSchema.parse(args); return await getRangeValues(filePath, sheetName, range); },
- src/index.ts:496-500 (registration)Tool declaration in the list of available tools for ListToolsRequestSchema, including name, description, and JSON schema derived from Zod schema.{ name: "get_range_values", description: "指定された範囲のデータを取得します", inputSchema: zodToJsonSchema(GetRangeValuesSchema) },
- src/index.ts:120-125 (helper)Helper function to validate the format of the range string (e.g., A1:C3) using a regex pattern. Called at the start of the handler.function validateRangeAddress(range: string): void { const rangePattern = /^[A-Z]+[1-9]\d*:[A-Z]+[1-9]\d*$/; if (!rangePattern.test(range)) { throw new Error(`無効な範囲指定: '${range}'。正しい形式: A1:C3, B2:D10など`); } }
