external links corruption by new Excel
There was a specification change in Excel, and in the .zip\xl\externalLinks, such as externalLink1.xml, there is a new line around line 4 that reads
<xxl21:alternateUrls><xxl21:absoluteUrl r:id="rId2"/></xxl21:alternateUrls>
is now added. This causes external links corruption by using openpyxl.
This code is added when entering or editing a cell with an external link by using Excel App.
Please fix this issue in the next version. (Machine Translation)
