Exporting HTML to Excel can be done using various Java libraries. The HTML-EXPORTER library, for example, allows you to export CSS-styled HTML to formats like XLSX, ODS, and PDF. It initially focused on exporting to Excel and Open Office Calc, as there wasn't a suitable HTML-to-spreadsheet exporter available for Java.

You can also use the Spire.XLS for Java library, which provides a Workbook.loadFromHtml() method to load an HTML file. This method can then be saved to Excel format using Workbook.saveToFile(). This library also allows you to insert HTML strings directly into Excel cells using the CellRange.setHtmlString() method.

Alternatively, you can use jsoup and Apache POI to convert an HTML table to an Excel file. This approach is useful when you need to generate Excel files in multiple places within your application. To use this method, you'll need to parse the HTML data, use Apache POI to prepare the Excel file, and then parse the header and table data to pass it to the POI API.

There are several Java libraries that can help you export HTML to Excel. One such library is HTML-EXPORTER, which provides a simple way to export CSS styled HTML to various formats, including XLSX, ODS, and PDF.

This library has been specifically designed to work with Excel (via POI) and Open Office Calc (via the ODS Toolkit), as these formats are not easily exportable from HTML using existing libraries.

To use this library, you'll need to create an object of the Workbook class and then load an HTML file using the Workbook.loadFromHtml() method. This method allows you to load an HTML file and convert it to Excel format.

Alternatively, you can use the Spire.XLS for Java library, which provides a Workbook.loadFromHtml() method for loading an HTML file. Once loaded, you can save the HTML file in Excel format using the Workbook.saveToFile() method.

The HTML-EXPORTER library also provides some convenience methods around the existing xhtmlRenderer/flying saucer library for PDF generation. This makes it easy to export HTML to PDF format using this library.

Here are some examples of the types of reports you can generate using the HTML-EXPORTER library:

Handling dates can be a bit tricky when exporting HTML to Excel. To create a date/time cell, use the data-date-cell-format attribute so the text value of the table cell can be parsed to a Java date.

The data-date-cell-format attribute is a must when working with dates, as it allows Excel to recognize and format the date correctly.
