Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Excel Workbook Manager - Read and Write xlsx and csv Files.

Readme

@cweijan/exceljs

这是面向 vscode-office/Office Viewer 使用场景维护的 ExcelJS 分支,用于读取、编辑和写出 XLSX 工作簿。

主要变更

  • 包名调整为 @cweijan/exceljs
  • 修复 Windows 环境或部分打包器生成的 XLSX 中反斜杠路径导致的文件解析问题。
  • 修复 SpreadsheetDrawing 使用默认命名空间时无法解析图片锚点的问题,例如 <wsDr><oneCellAnchor> 等无 xdr: 前缀的合法 drawing XML。
  • 保留 ExcelJS 的核心 Workbook、Worksheet、Cell、Style、Image、CSV/XLSX 读写能力,并提供浏览器构建入口。

安装

npm install @cweijan/exceljs

导入

import ExcelJS from '@cweijan/exceljs';

读取 XLSX

import ExcelJS from '@cweijan/exceljs';

const workbook = new ExcelJS.Workbook();
await workbook.xlsx.load(arrayBuffer);

const worksheet = workbook.getWorksheet(1);
worksheet.eachRow((row, rowNumber) => {
  console.log(rowNumber, row.values);
});

写出 XLSX

import ExcelJS from '@cweijan/exceljs';

const workbook = new ExcelJS.Workbook();
const worksheet = workbook.addWorksheet('Sheet1');

worksheet.columns = [
  {header: 'Name', key: 'name', width: 20},
  {header: 'Value', key: 'value', width: 16},
];

worksheet.addRow({name: 'Example', value: 123});

const buffer = await workbook.xlsx.writeBuffer();

常用操作

单元格

worksheet.getCell('A1').value = 'Hello';
worksheet.getCell('B1').value = 100;
worksheet.getCell('B1').numFmt = '#,##0.00';

样式

worksheet.getCell('A1').font = {bold: true, color: {argb: 'FF000000'}};
worksheet.getCell('A1').alignment = {vertical: 'middle', horizontal: 'center'};

合并单元格

worksheet.mergeCells('A1:C1');
worksheet.getCell('A1').value = 'Merged Title';

图片

const imageId = workbook.addImage({
  buffer: imageBuffer,
  extension: 'png',
});

worksheet.addImage(imageId, {
  tl: {col: 0, row: 0},
  ext: {width: 160, height: 90},
});

CSV

const workbook = new ExcelJS.Workbook();
await workbook.csv.readFile('data.csv');
await workbook.csv.writeFile('output.csv');
