读取表格数据(meeeyo.com):

The ReadExcelData node is designed to facilitate the extraction of data from Excel spreadsheets, allowing you to specify a particular range of rows and columns to read. This node is particularly useful for those who need to process or analyze data stored in Excel files without manually opening and navigating through the spreadsheet. By automating the data retrieval process, it saves time and reduces the potential for human error.

sheet_name

This parameter indicates the name of the sheet within the Excel file from which data will be read. It allows you to target specific sheets in a workbook. The default value is "Sheet1", and it should match the exact name of the sheet in the Excel file.

row_range

This parameter defines the range of rows to be read from the specified sheet. You can specify a single row or a range using a hyphen (e.g., "2-3"). The default value is "2-3", and it ensures that only the desired rows are processed.

col_range

This parameter specifies the range of columns to be read from the sheet. Similar to row_range, you can define a single column or a range using a hyphen (e.g., "1-4"). The default value is "1-4", allowing you to focus on specific columns of interest.
