node读取excel并转化存入mysql

示范excel的demo

先导入node-xlsx

npm install node-xlsx
const xlsx = require("node-xlsx")

读取excel的数据并进行数据转化

router.get("/commit", async (ctx, next) => {
	const m = xlsx.parse('./commit/2.xlsx')
	let table = new Array()
	m.forEach(item => {
		for(let i = 1; i < item['data'].length; i++) {
			let arr = new Array()
			for(let o = 9; o < item['data'][i].length; o++) {
				const t = item['data'][i][o] ? item['data'][i][o] + '--' : item['data'][i][o]
				arr.push(t)
			}
			table[i - 1] = {
				"dishes": item['data'][i][0],
				"introduce": item['data'][i][1],
				"ingredients": item['data'][i][2],
				"label": item['data'][i][3],
				"tips": item['data'][i][4],
				"hor": item['data'][i][5],
				"way": item['data'][i][6],
				"time": item['data'][i][7],
				"flavor": item['data'][i][8],
				"steps": arr
			}
		}
	})
	ctx.body = util.success(null, "新增成功")
})

数据转化并存入mysql

router.get("/commit", async (ctx, next) => {
	const m = xlsx.parse('./commit/2.xlsx')
	m.forEach(item => {
		for(let i = 1; i < item['data'].length; i++) {
			let arr = new Array()
			for(let o = 9; o < item['data'][i].length; o++) {
				const t = item['data'][i][o] ? item['data'][i][o] + '--' : item['data'][i][o]
				arr.push(t)
			}
			// 写入mysql
			const sql = `
				insert into daemon_food
					(dishes, introduce, ingredients, label, tips, hor, way, time, flavor, steps)
				values
					("${ item['data'][i][0] ?? null }",
					 "${ item['data'][i][1] ?? null }",
					 "${ item['data'][i][2] ?? null }",
					 "${ item['data'][i][3] ?? null }",
					 "${ item['data'][i][4] ?? null }",
					 "${ item['data'][i][5] ?? null }",
					 "${ item['data'][i][6] ?? null }",
					 "${ item['data'][i][7] ?? null }",
					 "${ item['data'][i][8] ?? null }",
					 "${ arr ?? null }")
			`
			query(sql)
		}
	})
	ctx.body = util.success("", "新增成功")
})
