Hi, I’ve been using Jekyll for a few years. Now I want to upgrade to 4.2 and I have problems with the MD-HTML parser from Jekyll code to HTML. I have been using redcarpet and the code does not work with other markdown renderers like kramdown. Is there any way to use redcarpet or another better markdown parser? I think the main problem is that I am using csv-database in some FOR loops! Is there anyone who has the same problems or a solution? Kind regards Norbert ---

Is “csv-database” a particular feature of Redcarpet? Certainly Kramdown can be used in a Liquid loop that accesses CSV data from Jekyll’s `_data` directory. Here’s an older topic that discusses the removal of alternate Markdown engines: > [@Jekyll 4.0: Many Markdown engines removed. Reason?](https://talk.jekyllrb.com/t/jekyll-4-0-many-markdown-engines-removed-reason/5912): > > I’ve finally got around to upgrading my blog from Jekyll 1.5(!) to a more modern version of Jekyll. However I notice that Jekyll 4.0 dropped support for the RDiscount and Redcarpet markdown engines, leaving only(?) the Kramdown engine. I happen to use the RDiscount engine and I’m pretty sure that changing the engine of my site will break lots of old posts in subtle ways. Is there a reason that support was dropped? The [PR](https://github.com/jekyll/jekyll/pull/6988) dropping the support didn’t mention a rationale. Neither did the [release …](https://jekyllrb.com/news/2019/08/20/jekyll-4-0-0-released/) ---

Hi chuckhoupt, thank you very much for your reply. Sorry, but I don’t understand this decision, because I read that redcarpet is a long term project in Git. Well i want a long term solution though! Can I ask you what you mean: Is it a possibility that I try to convert my csv data to xml format data to use in kramdown or would a csv usage somehow still be possible? Do you have any idea? Thanks Norbert ---

CSV data works the same in Jekyll 3 and 4, irrespective of Markdown processor used. To be clear, here’s an example (untested code): File `_data/contacts.csv`: ```auto name, phone Alice, 555-1111 Bob, 555-2222 ... ``` Example Liquid loop to create Markdown list: ```auto # Contact List {% for contact in site.data.contacts -%} - Name: {{ contact.name }} Phone: {{ contact.phone }} {%- endfor %} ``` Is this how you are using CSV data in Jekyll? Or some other mechanism? ---

Hi Chuck, yes I do the same mechanism (but without “-%” ?) with redcarped, but with kramdown it doesn’t work :-(! I will test the code and answer you afterwards! Thanks Norbert {% for pictdb2 in site.data.pictdb2s %} {% if pictdb2.status contains “whng” %} ``` {% endif %} ``` {% endfor %} ---

I added a tutorial to the Jekyll docs site on how to load a CSV and render it as HTML Hope that helps > **[Tabulate CSV Data](https://jekyllrb.com/tutorials/csv-to-table/)** > > This tutorial shows how to use Jekyll to read a CSV and render the data as an HTML table. ```auto {% for row in site.data.authors %} {% if forloop.first %} {% for pair in row %} {% endfor %} {% endif %} {% endfor %}
{{ pair[0] }}
``` And if you want a table you could use `ul` and each row is `li`. And then add ul and li inside that for each value in a row ---

` Inside this `
`, there’s an unclosed `
`. Possibly that might cause output differences between Redcarpet and Kramdown?
