Question

我撒谎使用bash将数据从cvs导入json文件示例Cvs

"Product ID";"Product Name";"Price";"Description";
"1;"Example";"200";"Descripcion here...";
"2;"Example2";"300";"Some here...";

我想要这样的东西：

{
"title":"Example",
"price":200,
"description": {
      "plain_text": "Some here..."
   },
"Predifined":static content,
"Another Predifined":static content,
}

这是我尝试使用的脚本

我如何做到这一点？

Answer 1

修正输入内容后，以分号正确分隔：

jq -R 'split(";")
| map(gsub("^\"|\"$";""))
| {title:.[1],
   price: .[2],
   description: { plain_text: .[3] }}' input.csv

产量：

{
  "title": "Product Name",
  "price": "Price",
  "description": {
    "plain_text": "Description"
  }
}
{
  "title": "Example",
  "price": "200",
  "description": {
    "plain_text": "Descripcion here..."
  }
}
{
  "title": "Example2",
  "price": "300",
  "description": {
    "plain_text": "Some here..."
  }
}

好吧，先前的jq答案更加优雅。我仅使用bash进行了此操作...自从完成后，我还是把它放在这里了，但是在收到@peak的好回答后，我感到有点傻。

对于OP，第一个是免费的。对于将来的问题，此处的用户会帮助，但是您必须开始使用，并面对一个需要帮助;-）

的特定问题。

#!/bin/bash

csvfile='input.csv'

# Make sure the file exists
if [ ! -f $csvfile ]
then
    echo "ERROR: file $csvfile does not exist."
    exit 1
fi

# Read the input file line per line
while read line
do
    # Capture the information out of the line, fields separated by ;
    IFS=';' read pid pname price desc <<< $line

    # Output the JSON for this line
    echo '{'
    echo "    \"title\":$pname,"
    echo "    \"price\":$price,"
    echo "    \"description\": {"
    echo "        \"plain_text\":$desc"
    echo "    },"
    echo "    \"Predifined\":\"static content\","
    echo "    \"Another Predifined\":\"static content\""
    echo '}'

    # Just to split the line's output
    echo ""
done <$csvfile

哪个产生以下输出：

{
    "title":"Product Name",
    "price":"Price",
    "description": {
        "plain_text":"Description"
    },
    "Predifined":"static content",
    "Another Predifined":"static content"
}

{
    "title":"Example",
    "price":"200",
    "description": {
        "plain_text":"Descripcion here..."
    },
    "Predifined":"static content",
    "Another Predifined":"static content"
}

{
    "title":"Example2",
    "price":"300",
    "description": {
        "plain_text":"Some here..."
    },
    "Predifined":"static content",
    "Another Predifined":"static content"
}

同一脚本的第二版，该脚本会将每个产品部分输出到其自己的JSON文件中。请注意，我删除了CSV文件的第一行，因为它只是标题，并且我不想为标题创建文件。

#!/bin/bash

csvfile='input.csv'

# Make sure the file exists
if [ ! -f $csvfile ]
then
    echo "ERROR: file $csvfile does not exist."
    exit 1
fi

# Read the input file line per line
sed '1d' $csvfile | while read line
do
    # Capture the information out of the line, fields separated by ;
    IFS=';' read pid pname price desc <<< $line

    # Strip the " from $pid and define the output filename
    output_filename="$(echo $pid | tr -d '"').json"

    # Output the JSON for this line
    echo '{'                                               >$output_filename
    echo "    \"title\":$pname,"                          >>$output_filename
    echo "    \"price\":$price,"                          >>$output_filename
    echo "    \"description\": {"                         >>$output_filename
    echo "        \"plain_text\":$desc"                   >>$output_filename
    echo "    },"                                         >>$output_filename
    echo "    \"Predifined\":\"static content\","         >>$output_filename
    echo "    \"Another Predifined\":\"static content\""  >>$output_filename
    echo '}'                                              >>$output_filename

    # Just to split the line output
    echo ""                                               >>$output_filename
done

有人可能会评论说，使用此处文档而不是像这样执行多个echo语句会更有效，但是我发现此处文档使缩进变得混乱，并且我从原始脚本开始，它的速度更快。 / p>
