ExcelJS VS jsPDF

For exporting to Excel from Javascript, I use ExcelJS

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.

If you want to go the JavaScript route on the client-side, there is ExcelJS.

I personally have used https://github.com/exceljs/exceljs in the past.

It looks like exceljs is able to word directly with buffers: https://github.com/exceljs/exceljs#reading-xlsx

jsPDF is a popular JavaScript PDF generator that allows users to generate PDF files in the web browser dynamically. The library is well-maintained, stable, easy to use, and has rich documentation.

I haven't had to generate PDF files from the browser, but jsPDF looks promising.

So, as advised on the github page https://github.com/parallax/jsPDF i tried to source the new version of jsPDF using either the first or second src that you see in comment in the code below.

was working fine. But it seems this version does not have the function to do dashed lines, so i wanted a newer version. I tried downloading the folder of the newest one, or tu put : as mentionned in this page : https://github.com/parallax/jsPDF, but now i got a bug when i try to create the pdf and the code stops at the instruction var doc = new jsPDF(); I hope have i been clear, sorry i'm kind of trying out things...

You can use the .NET built-in datagrid, write your own .csv export (it's about 15 lines of code), and use jsPDF to convert the datagrid content to pdf using JavaScript.

Didn't try but there is https://github.com/mozilla/pdf.js to read and https://github.com/parallax/jsPDF to write back so I imagine it could all be done in the browser, no app required. I'm not sure if there is already a project that combine both and use the canvas as a sketching support but have a look and if there isn't one I might prototype as it could be interesting for the PineNote.
