Hi I've had this problem since last year. I tried all the solutions everyone offered elsewhere (ie copy paste the whole thing to a new sheet), but even then, after a couple of weeks the same problem arises (without any changes on the sheet). Google has not fixed this yet. I know from other forums, etc that lots of people have the same problem for years now...
HELP !
I have used google sheets to import stock prices from bloomberg.com and I am using the following importxml formula for a number of stocks (each formula pulls the data from near identical web pages). I only use 15-20 similar formulas, so i can't be a processing power issue. The problem is that by a completely random rate, some formulas return #N/A "import internal error" whereas others return the result just fine. And it's not the same ones every time I open the sheet !!
This is the sample formula:
=ImportXml("http://www.bloomberg.com/quote/BND:US","//div[@class='price']")
May I stress that the xpath is correct and the formula DOES work normally.
Thanks
