如何验证 node.js 中的 csv 文件？

[英]How to validate a csv file in node.js?

原文 2016-07-06 19:12:23 2 1 javascript/ node.js/ validation/ csv

I have a large csv file that I need to convert to json, and then store the data into neo4j.我有一个很大的 csv 文件，我需要将其转换为 json，然后将数据存储到 neo4j 中。 I am using the csv-parser plugin for node.js.我正在为 node.js 使用 csv-parser 插件。 This works fine if the csv is valid.如果 csv 有效，这可以正常工作。 However if it's not valid, then the data in neo4j gets scrambled.但是，如果它无效，那么neo4j 中的数据就会被打乱。 Therefore I need to validate the file, before I can send it into my database.因此，我需要验证文件，然后才能将其发送到我的数据库中。 Are there any existing plugins available or is there a way for me to validate the csv file myself?是否有任何现有的插件可用，或者有没有办法让我自己验证 csv 文件？

You might look into checking out the API for csvlint您可能会考虑查看csvlint的 API

I also suggest checking out this similar answer .我还建议查看这个类似的答案。 (Below this answer also has good csvlint info, too) （在这个答案下面也有很好的 csvlint 信息）

There is also fast-csv which has some validation built in, which may help depending on your needs.还有fast-csv内置了一些验证，这可能会根据您的需要提供帮助。

Otherwise, finding a validator that caters to your specific needs may be difficult, and I suggest writing editing your node script to validate it for yourself.否则，找到满足您特定需求的验证器可能会很困难，我建议您编写编辑节点脚本来自己验证它。

Update: I would also like to recommend Papa Parse , which has several parsing options.更新：我还想推荐Papa Parse ，它有几个解析选项。
