Similar story here and with many of our customers. It's been radio silence with larger banks (Chase) and community banks. It's rumored that, just like how BofA prioritized companies with active business loans, other banks are giv

Performance is affected by a myriad of factors, many of which aren't visible by looking at the worksheet. For example, XLS/XLSX support a special "shared formula" representation which tells Excel that a formula is struct

Shameless plug: we ( https://sheetjs.com/ ) offer that as one of our paid builds. In conjunction with our JS parser https://github.com/SheetJS/js-xlsx , you can modify cell values / formulae and re

It isn't as simple as that. There are numerous equivalent representations of the same underlying content (same data, same styling, same charts, etc) that have wildly different XML representations. You need a content-aware diffing to

Aside from Excel's built-in "Track Changes" features (which stores the revision log within the file), the "Spreadsheet Compare" tool that ships with Excel is a decent diff engine that can be paired with any VCS. Sh

".docx is a bad example, because it was standardized" This is not 100% correct. A large part of the format is standardized in ECMA-376 and ISO/IEC 29500, but many details are implementation-dependent. Many of those details

The point, as we've made clear to Juan Picado and other recipients like Kir Belevich of SVGO ( https://twitter.com/deepsweet/status/1120290773625450501 ) is a token of appreciation. We don't want to creat

Verdaccio is an incredible tool. We ( https://sheetjs.com ) use it in production for distributing node modules to customers. Before verdaccio, we used to post tarballs that customers would download and use, but that became cumber

Also worth noting the downside of scale: some opportunities are "too small" for a Microsoft or Google to pursue. Google revenue for 2018 was $136.8B. Extra effort to possibly address a small niche segment of a market, that would

First off: awesome work! Correctly reading the data from XLSX is a lot more complex than described or implemented here, mostly because Excel is so robust in reading files and there are many sloppy writers. If you're interested, there&

There's a better way to frame this: Do you think an open source project creates a perpetual obligation? Even if many other developers depend on your project, are you forced to continue or can you walk away? If you assume you can walk

Your interpretation is far from the original point "There's nothing wrong with open source as long as you are honest to yourself regarding the intentions." If you're entering OSS to make money, it's incumbent upon

Start from the projects you are using. You might find that many of them are primarily one-man efforts and could use some support. For example, we use verdaccio ( https://www.verdaccio.org/ ) as a private NPM server. IT was
