Excel - Json - Joomla

A contribution to TimelineJS3

3 years ago I developed an Excel Based (VBA driven) routine to convert an Excel Worksheet to a JSON file which can be used instead of GoogleSheets; The results can be viewed at : https://oathlawtannadice.org.uk/hidden/tannadice-church-1500-1900-ad#event-things-are-about-to-change- (TimelineJS3 Version 3.8.21) (The site is developed using Joomla, TimelineJS3 called from Joomla Article)

Currently looking to move the site to Joomla V 4 (now moved) and checking out TimelineJS3.
Installed Locally (WAMPSERVER/Locahost) the Timelines display using latest version of TimeLineJ3 (3.8.21) with minor issues as noted:

a. TimelineJS3 options parameter 'Ease' causes error - Commenting out resolves
b. Re-write of Javascript prevents coloured markers - may be resolved in future (Now resolved - see #798)
c. Re-write of Javascript uses SANATIZE for html - needed slight change to HTML on one slide - move 'Style' to CSS

In Summary the EXCEL to JSON routine is valid for lastest version of TimelineJS3
The EXCEL routine also has a function to create a Slide Entry in a vertical format and insert into the standard format
Anyone interested in the above can request the EXCEL Sheets / Joomla details

The report mentions TimelineJS3 3.8.21, the Ease option error, and the attached OTProject01.txt JSON; begin by reproducing the issue with the local Joomla/WAMP setup. A specific change and reproducible test are still needed before “done” can be defined.
