This invention discloses a method for merging multiple Excel spreadsheets, specifically relating to the field of
data processing technology, including the following steps: S1, Spreadsheet preprocessing and folder creation: Create a new folder, copy the target Excel spreadsheets to the folder, select any spreadsheet, insert a blank row, and save; S2, Batch import spreadsheets: Import all spreadsheets in the folder using Excel's PowerQuery editor, specify the worksheet, filter the data, and upload it; S3,
Data processing: Copy the uploaded data, paste it as "values" into a new worksheet, and remove formatting interference; S4, Subtotal calculation: Use Excel's subtotal function to set grouping fields, summary items, and
calculation methods to generate the merged calculation results; S5, Filter or further process the summary results. This method is suitable for batch data calculations, greatly reducing the hassle of manually opening,
copying, and pasting each item, quickly completing data merging, and achieving 100% accuracy in calculations involving thousands of spreadsheets. The batch calculation is highly efficient and fast, making it worthy of widespread promotion.
