Discuss conversion issues between HTML and Excel

HTML and Excel are currently very commonly used data processing formats. However, there are often situations where mutual conversion is required between different data platforms or applications. This article will discuss the conversion problem between HTML and Excel and provide readers with possible solutions.

For developers who use HTML language, converting HTML to Excel is usually very difficult. The reason is that Excel provides data in multiple formats and stores a bunch of information in cells, including formats, images, etc., which does not exist in HTML. To convert an HTML table to Excel, the best way is to convert it to CSV (Comma Separated Values). This format consists of a plain text file with one record per row and columns separated by commas.

Let’s first take a look at how to convert HTML tables into CSV format. Taking a typical HTML table as an example, there is the following header information:

<table>
  <thead>
    <tr>
      <th>姓名</th>
      <th>性别</th>
      <th>年龄</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>小明</td>
      <td>男</td>
      <td>18</td>
    </tr>
    <tr>
      <td>小红</td>
      <td>女</td>
      <td>20</td>
    </tr>
    <tr>
      <td>小王</td>
      <td>男</td>
      <td>22</td>
    </tr>
  </tbody>
</table>

And converting it to CSV requires the following steps:

1. Create a plain text file and put it in it Open anywhere.
2. Copy each row in the HTML table row by row, separate the table elements with commas, and ensure that there are no commas at the end of the row.
3. Save the file and rename it to .csv format.

After converting the HTML table into CSV format, the next step is to convert it into Excel. Excel is a very powerful program that supports a variety of data input and output formats. Excel can also easily import the CSV format we use. Just open it in Excel, then navigate to the corresponding .CSV file through the File-Open file menu item, select the file, and then select the relevant parameters to complete the conversion.

Some open source tools and libraries can also be used to convert HTML tables to Excel. The most popular of these is the JavaScript plug-in "table2excel", which can convert tables into Excel and CSV formats. The advantage of this plugin is that it is very easy to use and very compatible in all major browsers.

In addition, by using online tools, HTML tables can be converted to Excel or CSV format. Most online tools are very simple and easy to use. Just select the HTML table file and upload it to the online tool server.

In short, HTML and Excel are not only common data processing formats, but also important tools for data processing today. These data formats need to be converted between different data platforms or applications. In this article, we learned about ways to convert HTML tables to Excel.
