When Html Writer outputs a cell with a boolean value, the result will either be 1 or null-string; neither of these is optimal for anyone looking at the resulting html. Html Reader already has the ability to recognize data types using the html `data-type` attribute, but Html Writer doesn't use it. This PR adds the ability to generate that attribute for booleans. It will generate a string value appropriate for the locale when it encounters a boolean. Html Reader, when it encounters `data-type="b"`, will interpret the result as true if the value is 1 or a string value recognized as true in any locale; it will interpret the result as false if the value is 0, null-string, null, or a string value recognized as false in any locale; if none of the above, it will leave the value as an unchanged string. So, Reader will wind up with the correct result even if its locale is different than what Writer used. Because this is a breaking change, it is opt-in. You need to call `Writer::setBetterBoolean(true)` in order for it take effect. The current default value for that property is false. When it is time to introduce breaking changes (see PR #4240), the default will be changed to true.
PhpSpreadsheet
PhpSpreadsheet is a library written in pure PHP and offers a set of classes that allow you to read and write various spreadsheet file formats such as Excel and LibreOffice Calc.

Patreon
I am now running a Patreon to support the work that I do on PhpSpreadsheet.
Supporters will receive access to articles about working with PhpSpreadsheet, and how to use some of its more advanced features.
Posts already available to Patreon supporters:
- The Dating Game
- A look at how MS Excel (and PhpSpreadsheet) handle date and time values.
- Looping the Loop
- Advice on Iterating through the rows and cells in a worksheet.
And for Patrons at levels actively using PhpSpreadsheet:
- Behind the Mask
- A look at Number Format Masks.
The Next Article (currently Work in Progress):
- Formula for Success
- How to debug formulae that don't produce the expected result.
My aim is to post at least one article each month, taking a detailed look at some feature of MS Excel and how to use that feature in PhpSpreadsheet, or on how to perform different activities in PhpSpreadsheet.
Planned posts for the future include topics like:
- Tables
- Structured References
- AutoFiltering
- Array Formulae
- Conditional Formatting
- Data Validation
- Value Binders
- Images
- Charts
After a period of six months exclusive to Patreon supporters, articles will be incorporated into the public documentation for the library.
PHPExcel vs PhpSpreadsheet ?
PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.).
Because all efforts have shifted to PhpSpreadsheet, PHPExcel will no longer be maintained. All contributions for PHPExcel, patches and new features, should target PhpSpreadsheet master branch.
Do you need to migrate? There is an automated tool for that.
