At the end of last year, foreign media reported that due to strong requests from community users, Microsoft was considering adding Python as an official Excel scripting language . However, at the Build 2018 developer conference yesterday, Microsoft did not disclose the news about Python support, but announced that Excel added JavaScript support, which means that developers can now run native JavaScript custom functions in Excel.
That is to say, developers can use JavaScript code to customize Excel formulas, then insert and call these formulas from Excel tables, and calculate the table data through the JavaScript interpreter, instead of using Excel's own calculation engine.
Microsoft says that Office developers have long wanted to be able to write JavaScript custom functions in Excel to do some math, bank account data, stock data, and more, a move that will give them more flexibility to customize Excel.
However, this feature has not been officially released, and is currently only available in the Excel Developer Preview for Windows and Mac, as well as in the Excel online version. Users need to join Office Insiders and install a custom add-in before they can experience it.
