• excelize

  15 17,384 8.8 Go

  Go language library for reading and writing Microsoft Excel™ (XLAM / XLSM / XLSX / XLTM / XLTX) spreadsheets

  

Project mention: Recommend a powerful excel processing library, @zurmokeeper/exceljs, which supports encryption and decryption of xlsx files and flexible setting of multiple table headers when exporting, etc. | /r/node | 2023-07-01

Then I found out that WPS only supports ecma376 standard encrytion for xlsx files. Then I referred to the official documentation and libraries in other languages, such as msoffcrypto-tool written in python. msoffcrypto-tool) and go's excelize. Since I don't know much about encryption and decryption, the process of implementation is also a bit of a twist.

Project mention: When XML in Word Became Illegal | news.ycombinator.com | 2023-10-12

It's also country specific.

I work on Excel library and the text to number/date feature was one of less fun things to implement at least semi-correctly.

I remember my comment on the PR back then:

• ONLYOFFICE

  ONLYOFFICE Docs is a free collaborative online office suite comprising viewers and editors for texts, spreadsheets and presentations, forms and PDF, fully compatible with Office Open XML formats: .docx, .xlsx, .pptx and enabling collaborative editing in real time.

  

Project mention: Ask HN: Why hasn't OnlyOffice see higher adoption than LibreOffice? | news.ycombinator.com | 2024-02-24

Had never even heard of it.

And their website doesn't help at all - https://www.onlyoffice.com/ - At first, I thought it is selling some kind of add-on for Businesses to use with Microsoft Office. Then I clicked "Get it now" and saw a page that gives me options to download a Docker Image, or Cloud Images or VM Images. What the heck? Then I see the "GET OnlyOffice" link in the navigation menu and go to it - the menu pop-up talks about DocSpace, Enterprise, Workspace etc. etc. and asks to sign-in for cloud. Again, what the heck?? Then I go to the PRODUCT link that also pop-ups lot of options - like - Doc editors to integrate into your business platform .... ??? Then I see the "Desktop and Mobile Apps" option in it and click 'For Desktop'. And finally, here I found what I had been searching for - Get free desktop office suite for document editing and collaboration ( https://www.onlyoffice.com/desktop.aspx ).

When a website is designed to be "Enterprisey" - only targetting and catering to a particular audience, and totally ignores everyone else - I am not surprised it's userbase is limited.

• python-docx

  6 4,241 8.0 Python

  Create and modify Word documents with Python

  

Project mention: What Would Go in Your Dream Documentation Solution? | /r/technicalwriting | 2023-12-09

So, what I'd like to do is write a documentation package in Python to recreate what I've lost. I plan to build upon the fantastic python-docx and docxtpl packages, and I'll probably rely on pandas from much of the tabular stuff. Here are the features I intend to include:

• docx

  11 3,955 8.9 TypeScript

  Easily generate and modify .docx files with JS/TS with a nice declarative API. Works for Node and on the Browser.

Project mention: Ajuda docx | /r/programacao | 2023-06-19

• xlwings

  25 2,848 8.4 Python

  xlwings is a Python library that makes it easy to call Python from Excel and vice versa. It works with Excel on Windows and macOS as well as with Google Sheets and Excel on the web.

  

Project mention: Python in Excel: Combining the Power of Python and the Flexibility of Excel | news.ycombinator.com | 2023-08-23

Reading the headline, I initially thought that Microsoft bought the company behind XLWings [1], which also enables you to use Excel directly within Excel, even locally. Not affiliated in any kind to that company, just used it in the past.

• Ferdium

  216 2,567 9.1 TypeScript

  Ferdium is a desktop app that helps you organize how you use your favourite apps by combining them into one application.

  

Project mention: Sparkle: A software update framework for macOS | news.ycombinator.com | 2024-02-13

Also, as a different approach, to some degree Ferdium can act as a central place for various messaging platforms even if the integration that Pidgin (and Adium) and libPurple provided is not possible this way. Station is similar and a bit better but is in desperate need of developers. Both are FLOSS.

Project mention: Want to learn how to daily drive a linux distro as a humanities student | /r/linuxquestions | 2023-12-10

First of all, if you need to write a lot of files in the doc format, there's a lovely office suite called libreoffice! Also, cups is a decent print utility for most printers, I'd check that out as well.
