用 Node.js 和 C++ 移除 Excel 文件中工作表的现有 PrinterSettings

可能的使用场景

有时开发人员希望阻止Excel在保存的XLSX文件中包含打印机设置的*.bin*文件。打印机设置文件位于*“[file “root”]\xl\printerSettings”*。本文介绍了如何使用Aspose.Cells API移除现有的打印机设置。

删除Excel文件中工作表的现有打印设置

Aspose.Cells允许您移除Excel文件中不同工作表的现有打印机设置。以下示例代码说明了如何移除工作簿中所有工作表的现有打印机设置。请参阅其示例Excel文件，输出Excel文件，控制台输出以及屏幕截图以供参考。

示例代码

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// Source directory
const sourceDir = path.join(__dirname, "data");

// Output directory
const outputDir = path.join(__dirname, "output");

// Load source Excel file
const filePath = path.join(sourceDir, "sampleRemoveExistingPrinterSettingsOfWorksheets.xlsx");
const wb = new AsposeCells.Workbook(filePath);

// Get the sheet counts of the workbook
const sheetCount = wb.getWorksheets().getCount();

// Iterate all sheets
for (let i = 0; i < sheetCount; i++) {
// Access the i-th worksheet
const ws = wb.getWorksheets().get(i);

// Access worksheet page setup
const ps = ws.getPageSetup();

// Check if printer settings for this worksheet exist
if (ps.getPrinterSettings() != null) {
// Print the following message
console.log("PrinterSettings of this worksheet exist.");

// Print sheet name and its paper size
console.log("Sheet Name: " + ws.getName());
console.log("Paper Size: " + ps.getPaperSize());

// Remove the printer settings by setting them null
ps.setPrinterSettings(null);
console.log("Printer settings of this worksheet are now removed by setting it null.");
console.log("");
} // if
} // for

// Save the workbook
wb.save(path.join(outputDir, "outputRemoveExistingPrinterSettingsOfWorksheets.xlsx"));
