1. 3

I often end up in situations where I’ve have tabular data that I need to format for presentation in a browser. I’d need a tool that can take tabular data in various formats - simple space or character delimited fields (as is common with UNIX CLI commands), CSV, and JSON and generate a HTML or markdown table with the data.

I have found https://www.tablesgenerator.com/html_tables which is a nice tool, but it is web based and doesn’t provide a way for me to batch input data into it. Does a CLI equivalent that does that exist?

    This is language specific, so may not be what you’re looking for? (Golang, ported from a Ruby lib)

    But it has HTML and Markdown output.

      For those curious what I settled on, I ended up using the pandoc-placetable filter (http://hackage.haskell.org/package/pandoc-placetable) with Pandoc in a simple shell script that can read from STDIN or file, and outputs HTML. With this approach I could also produce Markdown tables from the CSVs as well.

      The script is available in my dotfiles: https://github.com/Stratus3D/dotfiles/blob/master/scripts/tools/csv2html

        I also just found this: http://jeroenjanssens.com/2013/09/19/seven-command-line-tools-for-data-science.html

        It shows a tool named csvlook, but I don’t think it can output Markdown or HTML tables.

          I don’t know it (and don’t endorse it, I’m very hesitant when it comes to unaudited npm packages) but after a quick search this seems like something you are looking for:


          Edit: I think I misread your question. Nevermind! Maybe this is something that can help you:


          It’s only csv unfortunately, but if you can find json and cli argument equivalents you can write your own simple shell script to incorporate all in one.

            It should be trivial to write a tool for this. Read from stdin, using your favourite language’s CSV parser, and print some HTML.

            There are a bunch of JSON to CSV tools, which you could perhaps use for JSON support. I would suspect that figuring out how to best use that will be harder than just modifying the program though.
