Convert XLS to XLSB Programmatically?

由 风流意气都作罢 提交于 2019-11-27 02:44:21
问题 I have a customer that needs to convert XLS files to XLSB. Has anyone done this programmatically, (with or without an add-on --- doesn't matter --- just need to be able to automate it)? I'm looking for a way to automate this. As a side note, the customer is asking about this because they use Sharepoint, and it seems it has a way to analyze XLSB files quicker and easier than XLS? I'm working to improve my Sharepoint knowledge, but in the meantime, I'm trying to find an answer to this XLSB

Some of my cells contain multiple lines of information (a list), so I can use "\n" in csv to indicate multiple lines within

node读写Excel操作

目支持写Excel的node.js模块： node-xlsx: 基于Node.js解析excel文件数据及生成excel文件； excel-parser: 基于Node.js解析excel文件数据，支持xls及xlsx格式文件； excel-export : 基于Node.js将数据生成导出excel文件，生成文件格式为xlsx； node-xlrd: 基于node.js从excel文件中提取数据，仅支持xls格式文件。 下面通过node-xlsx模块来操作Excel文件。 1 、安装 node-xlsx 模块 每次npm的时候，走国外的镜像，非常的慢，甚至安装失败，可以配置一下 通过改变默认npm镜像代理服务，以下三种办法任意一种都能解决问题，建议使用第三种，将配置写死，下次用的时候不用重新配置。 通过config命令 npm config set registry https://registry.npm.taobao.org npm info underscore (如果上面配置正确这个命令会有字符串response) 命令行指定 npm --registry https://registry.npm.taobao.org info underscore 编辑 ~/.npmrc 加入下面内容 registry = https://registry.npm.taobao.org
