Question

我如何格式化它以使其适合csv格式？我不小心删除了我的表，现在我需要导出这些数据。

+-----+---------------------------------+-------------+-------------------+
| id  | email                           | firstName   | lastName          |
+-----+---------------------------------+-------------+-------------------+
|   6 | email@email.com                 | Person1     | Person1           |
|   7 | email2@email.com                | Person2     | Person2           |
|   8 | email3@email.com                | Person3     | Person3           |
+-----+---------------------------------+-------------+-------------------+

这是我之前制作的文本文件，所以如何删除这些行，使其如下所示：

"6","email@email.com","Person1","Person1"

Answer 1

您可以在Excel中手动执行此操作（打开文件，数据 - ＆gt;文本到列，固定宽度。

正则表达式，2个选项：

替换东西：

s/^\|\s+/"/;
s/\s+\|\s+/","/g;
s/\s*\|$/"/;

匹配东西：

s/^\|\s+(\d+)\s+\|\s+(\S+)\s+\|\s+(\S+)\s+\|\s+(\S+)\s+\|$/"$1","$2","$3,"$4"/

当然，确切的语法取决于您使用的语言。

Javascript中的答案 - RegEx （未提及任何语言，picked JS by looking at your profile）

[\w\s.@]+(?=\|)

对于特定情况，仅允许\w，\s，.，@。您可以根据自己的方便允许更多角色

对于多行文字 - TextArea

var str = $('#regex_string').val()

或对于单行 - Enter或\n已删除，使其成为将其存储在变量中的单行

var str = '+-----+---------------------------------+-------------+-------------------+| id  | email                           | firstName   | lastName          |+-----+---------------------------------+-------------+-------------------+|   6 | email@email.com                 | Person1     | Person1           ||   7 | email2@email.com                | Person2     | Person2           ||   8 | email3@email.com                | Person3     | Person3           |+-----+---------------------------------+-------------+-------------------+'

var extractValidString = str.match(/[\w\s.@]+(?=\|)/g).join("").trim().split(/\s+/)
//output ["id", "email", "firstName", "lastName", "6", "email@email.com", "Person1", "Person1", "7", "email2@email.com", "Person2", "Person2", "8", "email3@email.com", "Person3", "Person3"]

//to remove Headers - id, email, firstName, lastName
extractValidString.splice(0,4)

//extract all rows
var arr = [];
while(extractValidString.length>0) {
    //Extract set of 4 elements as you have only 4 columns
    //change second no to allow other columns as per your requirement
    arr.push(extractValidString.splice(0,4))
}

//output
[Array[4], Array[4], Array[4]]
0: Array[4]
    0: "6"
    1: "email@email.com"
    2: "Person1"
    3: "Person1"
    length: 4
    __proto__: Array[0]
1: Array[4]
    0: "7"
    1: "email2@email.com"
    2: "Person2"
    3: "Person2"
    length: 4
    __proto__: Array[0]
2: Array[4]
    0: "8"
    1: "email3@email.com"
    2: "Person3"
    3: "Person3"
    length: 4
    __proto__: Array[0]
length: 3
__proto__: Array[0]
