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 🙏

@yangchanghao/xlsx-transformer

基于sheetJs封装,实现 json 数组和 excel 表格的相互转换以及上传下载功能

1.下载

(1)npm 方式下载:

npm install @yangchanghao/xlsx-transformer -S

(2)yarn 方式下载:

yarn add @yangchanghao/xlsx-transformer

2.如何使用

提示若出现 typescript 报错 @yangchanghao/xlsx-transformer 模块找不到,可以在声明文件 .d.ts 中添加如下代码

declare module '@yangchanghao/xlsx-transformer'

1.excel 表格转换成 json 数组

import { uploadFile, excel2Json } from '@yangchanghao/xlsx-transformer'
import type { IDicts } from '@yangchanghao/xlsx-transformer'

/** 数据翻译字典 */
const excelDicts: Array<IDicts> = [
  { label: 'name', value: '姓名' },
  { label: 'student_no', value: '学号' },
  { label: 'id', value: '序号' },
  { label: 'total_words', value: '总字数' },
  { label: 'true_percent', value: '正确率' },
  { label: 'time', value: '用时' },
]

/** 上传文件 */
uploadFile().then((file: Blob) => {
  /** 如果配置了dicts,那么就会根据excelDicts反向把表格里的汉字转换成英文,不配置则什么都不做 */
  excel2Json(file, { dicts: excelDicts })
    .then((res) => {
      console.log('JOSN数组是', res)
    })
    .catch((err) => console.log(err))
})

2.根据 json 数组生成 excel 表格并下载

import { donwLoadFile, json2Excel } from '@yangchanghao/xlsx-transformer'

const resultList: Array<Record<string, any>> = [
  { name: '学生1', student_no: 20147477, id: 1, total_words: 100, true_percent: 0.92, time: 3 },
  { name: '学生2', student_no: 20147472, id: 2, total_words: 100, true_percent: 0.92, time: 3 },
  { name: '学生3', student_no: 20147475, id: 3, total_words: 100, true_percent: 0.92, time: 3 },
  { name: '学生4', student_no: 20147471, id: 5, total_words: 100, true_percent: 0.92, time: 3 },
  { name: '学生5', student_no: 20147470, id: 4, total_words: 100, true_percent: 0.92, time: 3 },
]

/** 根据json数组和翻译字典数组生成excel表格文件 */
/** 如果配置了dicts,那么就会根据excelDicts把表格里的英文转换成汉字,不配置则什么都不做 */
json2Excel(resultList, { dicts: excelDicts }).then((res) => {
  /** 下载excel表格,并设置表格文件名称 */
  donwLoadFile(res, '学生成绩表')
})
