<p>在CSV格式的字符串及其JavaScript对象表示形式之间进行相互转换。</p>
<h3>输入</h3>
<dl class="message-properties">
<dt>payload<span class="property-type">object | 数组 | 字符串</span></dt>
<dd>JavaScript对象数组或CSV字符串。</dd>

<h3>输出</h3>

<ul>
<li>如果输入是字符串它将尝试将其解析为CSV并为每行创建键/值对的JavaScript对象。然后该节点将为每行发送一条消息或者发送一条包含对象数组的消息。</li>
<li>如果输入是JavaScript对象它将尝试构建CSV字符串。</li>
<li>如果输入是简单值的数组则将构建单行CSV字符串。</li>
<li>如果输入是数组数组或对象数组则会创建多行CSV字符串。</li>

<h3>详细</h3>
<p>列模板可以包含列名称的有序列表。将CSV转换为对象时列名将用作属性名称。或者也可以从CSV的第一行中获取列名称。</p>
<p>转换为CSV时列模板用于标识从对象中提取的属性以及提取的顺序。</p>
<p>如果输入是数组,则列模板仅用于有选择地生成一行列标题。</p>
<p>只要正确设置<code>parts</code>属性,该节点就可以接受多部分输入。</p>
<p>如果输出多个消息,则将设置其<code>parts</code>属性并形成完整的消息序列。</p>
<p><b>注意:</b>列模板必须用逗号分隔,即使数据中已有了其他分隔符。</p>
