SheetJS js-xlsx VS HANDSONTABLE

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.

Handsontable is primarily known as a JavaScript grid library for business apps but the decision to include it in this article is not accidental. Although this tool doesn't offer as many text formatting options as Excel, it includes quite a lot of features for manipulating data typical of spreadsheets. The list of the most widely used Handsontable features includes operations on rows & columns (moving, hiding, resizing, freezing), CRUD actions, non-contiguous selection, data validation, export to file, and merging cells. You can also take advantage of more advanced capabilities such as multi-column sorting, data summaries, trimming rows, and nested headers.
