PDFKit VS SheetJS js-xlsx

PDFkit is one of the oldest and most well-established PDF libraries in the JavaScript ecosystem; it is still well-maintained, and regularly updated. This library is a popular option for creating and manipulating PDF documents in a server-side environment, typically using Node.js. It allows you to programmatically generate PDF files by defining each page's content, layout, and formatting.

pdfkit is a JavaScript PDF lib that allows web developers to create PDF documents programmatically. It provides a simple and intuitive API for generating basic PDFs.

Build a PDF generator using Kintone's REST API and a PDF library like PDFKit or PDFMake

https://pdfkit.org/ is pretty powerful, surprised to see no one has mentioned this so far.

If this is a concern for you, I suggest you look at projects like pdfkit, they allow you to compose the content of the pdf directly, without using another format (html) has an intermediate layer.

I use pdfkit at work

Then write a script to export the drag drop. Maybe use a browser function to save the page as a PDF. Or a NPM library using something like https://www.npmjs.com/package/pdfkit

Maybe pdfkit

ExcelJS and XLSX (SheetJS) are great libraries to work with XLSX files. The former I've found a bit easier to work with but less efficient in general.

Sure. I manipulate excel files programatically in the browser all the time. I don't really understand your exact workflow, but I use Javascript with xlsx and React.

Looking at the xlsx documentation, to parse files in the browser, rather than readFile, you use read, which is designed to parse binary data directly, rather than read from disk. There are a bunch of different formats if you go to the XLSX NPM page and scroll down to "Acquiring and Extracting Data". Importantly, it seems the data must already be serialized, so a Blob won't work, but we can work with that.

Last year, Bing and Edge erroneously flagged our website https://sheetjs.com/ as "dangerous": https://i.imgur.com/BvA3zrk.png

At the time, there was no "Safety Report" to indicate why Bing thought it was dangerous. The report page linked to https://www.bing.com/toolbox/bing-site-safety?url=https%3a%2... and it said "That web page doesn't exist"

To fix it, we had to register with "Bing Webmaster Tools" (https://www.bing.com/webmasters/about) and raise a support ticket.

Within a few days, the issue "resolved itself". It's possible that raising a ticket forced some automatic refresh of the indexed data for the domain.
