如何运行 Google 表格应用脚本，如果出现错误，则调用电子表格 function IMPORTXML() 来填充单元格？

Question

To get the price of bitcoin and other cryptocurrencies into my Google Sheets spreadsheet, I use this function:

=importJSON("https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd&ids=bitcoin","0.current_price")

where importJSON is a Google App Script provided by coingecko (see https://blog.coingecko.com/import-coingecko-cryptocurrency-data-into-google-sheets/ )

This works fine for a few lookups, but if the spreadsheet has many cryptocurrencies, a whole bunch of them will say "Error: Exceed maximum execution time (line 0)."

see picture

Is it possible to detect this error, and if there is an error, call this function instead:

=IMPORTXML("https://coinmarketcap.com/currencies/bitcoin","//div[@class='priceValue___11gHJ']")

The problem is that this is a Google Sheets function and I don't know how to call it from inside the Google Apps script inside the catch(err) code block.

Answer 1

You can do it wiht IFERROR

Sample formula:

=IFERROR(importJSON("https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd&ids=bitcoin","0.current_price"),IMPORTXML("https://coinmarketcap.com/currencies/bitcoin","//div[@class='priceValue___11gHJ']"))
