Show HN: Spreadsheet Timeline (my weekend project)

That&#x27;s a wonderful tool. Great and thanks for sharing!<p>I often make these same timelines in excel manually and paste them into a powerpoint.<p>I am curious to know the tech stack you used -- or if you have a github for scourcecode.

Looks very nice, but US date format will limit use for many. Needs an option for DD&#x2F;MM, (or ISO-8601).
