PR #2850 and PR #2851 added support for Worksheet Visibility to ODS. They work well when LibreOffice is used to open the spreadsheet. However, when Excel tries to open it, it reports corruption. Strictly speaking, this is not a PhpSpreadsheet problem, but, if we can fix it, we should. It took a while to figure out what's bothering Excel. I'm not sure that all of what follows is necessary, but it works. It appears that it wants the content.xml `style:automatic-styles` definition for the `table` (i.e. worksheet) to include a `style:master-page-name` attribute. That attribute requires a corresponding definition in the `office:master-styles` section in styles.xml, and that attribute likewise requires a definition in `office:automatic-styles`. The new entries in styles.xml can be used to specify things like header and footer. However, the ways that these are specified is distinctly different from what Excel (and therefore PhpSpreadsheet) does. Implementing that will be a good future project. However, for now, they will remain unsupported for Ods.
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.
