I want to get following data (marked in red) from following website.
Image of data I want to get in google sheet
WEBSITE: https://trendlyne.com/equity/PE/NIFTY50/1887/nifty-50/
I tried using importhtml and importxml functions. But I get errors like "could not fetch URL".
For example I used:
=importxml("https://trendlyne.com/equity/PE/NIFTY50/1887/nifty-50/","/html/body/div[3]/div[1]/div[2]/div[2]/div[1]/div")
I am using xPathFinder google chrome plugin to get xPathQuery.
This method is working for other websites, but not working on this one.
Please help. How can I get the data to my Excel sheet.
I tested the same method with other websites and it works but I get the same error with the website you're trying to get data from.
The error "Could not fetch url" basically means that Google is not able to import the content from this specific website. This site is rejecting Google's request to prevent web scraping, so this means that IMPORT functions will not work in this scenario.

I'm trying to see if it's possible to scrape data from Transfermarkt.com to import into a Google Sheets doc.
Currently, I'm trying to import the team data from a player's profile page (see example URL here: https://www.transfermarkt.co.uk/joao-palhinha/profil/spieler/257455) but in future may want to import other data as well.
I wonder if it's possible to scrape data in this way from Transfermarkt, but if it is, any advice on what I'm doing wrong would be very much appreciated!
Right now I'm using, =IMPORTXML(B1,"/html/body/div[3]/main/header/div[4]/div/span[1]/a") where the URL is in B1. I copied the Full XPath from the HTML, but have also tried this by copying just the XPath too.
It says Loading for a few seconds before returning N/A, with an error message 'Resource at URL not found'.
I'm expecting the result in this instance to be Fulham.
Thanks
I am trying to import data from the following website to Google Sheets. I want to import all the matches for the day.
https://www.tournamentsoftware.com/tournament/b731fdcd-a0c8-4558-9344-2a14c267ee8b/Matches
I have tried importxml and importhtml, but it seems this does not work as the website uses JavaScript. I have also tried to use Apipheny without any success.
When using Apipheny, the error message is
'Failed to fetch data - please verify your API Request: {DNS error'

Adapted from my answer to How to know if Google Sheets IMPORTDATA, IMPORTFEED, IMPORTHTML or IMPORTXML functions are able to get data from a resource hosted on a website? (also posted by me)
Please spend some time learning how to use the browsers developers tools so you will be able to identify
if the data is already included in source code of the webpage as JSON / literal JavaScript object or in another form
if the webpage is doing a GET or POST requests to retrieve the data and when those requests are done (i.e. as some point of the page parsing, or on event)
if the requests require data from cookies
Brief guide about how to use the web browser to find useful details about the webpage / data to import
Open the source code and look if the required data is included. Sometimes the data is included as JSON and added to the DOM using JavaScript. In this case it might be possible to retrieve the data by using the Google Sheets functions or URL Fetch Service from Google Apps Script.
Let say that you use Chrome. Open the Dev Tools, then look at the Elements tab. There you will see the DOM. It might be helpful to identify if the data that you want to import besides being on visible elements is included in hidden / not visible elements like <script> tags.
Look at Source, there you might be able to see the JavaScript code. It might include the data that you want to import as JavaScript object (commonly referred as JSON).
There are a lot of questions about google-sheets +web-scraping that mentions problems using importhtml and/or importxml that already have answers and even many include code (JavaScript snippets, Google Apps Script functions, etc.) that might save you to have to use an specialized web-scraping tool that has a more stepped learning curve. At the bottom of this answer there is a list of questions about using Google Sheets built-in functions, including annotations of the workaround proposed.
On Is there a way to get a single response from a text/event-stream without using event listeners? ask about using EventSource. While this can't be used on server side code, the answer show how to use the HtmlService to use it on client-side code and retrieve the result to Google Sheets.
As you already realized, the Google Sheets built-in functions importhtml(), importxml(), importdata() and importfeed() only work with static pages that do not require signing in or other forms of authentication.
When the content of a public page is created dynamically by using JavaScript, it cannot be accessed with those functions, by the other hand the website's webmaster may also purposefully have prevented web scraping.
How to identify if content is added dynamically
To check if the content is added dynamically, using Chrome,
Open the URL of the source data.
Press F12 to open Chrome Developer Tools
Press Control+Shift+P to open the Command Menu.
Start typing javascript, select Disable JavaScript, and then press Enter to run the command. JavaScript is now disabled.
JavaScript will remain disabled in this tab so long as you have DevTools open.
Reload the page to see if the content that you want to import is shown, if it's shown it could be imported by using Google Sheets built-in functions, otherwise it's not possible but might be possible by using other means for doing web scraping.
According to Wikipedia,
Web scraping, web harvesting, or web data extraction is data scraping used for extracting data from websites.
Use of robots.txt to block Web crawlers
The webmasters could use robots.txt file to block access to website. In such case the result will be #N/A Could not fetch URL.
Use of User agent
The webpage could be designed to return a special a custom message instead of the data.
Below there are more details about how Google Sheets built-in "web-scraping" functions works
IMPORTDATA, IMPORTFEED, IMPORTHTML and IMPORTXML are able to get content from resources hosted on websites that are:
Publicly available. This means that the resource doesn't require authorization / to be logged in into any service to access it.
The content is "static". This mean that if you open the resource using the view source code option of modern web browsers it will be displayed as plain text.
NOTE: The Chrome's Inspect tool shows the parsed DOM; in other works the actual structure/content of the web page which could be dynamically modified by JavaScript code or browser extensions/plugins.
The content has the appropriated structure.
IMPORTDATA works with structured content as csv or tsv doesn't matter of the file extension of the resource.
IMPORTFEED works with marked up content as ATOM/RSS
IMPORTHTML works with marked up content as HTML that includes properly markedup list or tables.
IMPORTXML works with marked up content as XML or any of its variants like XHTML.
The content doesn't exceeds the maximum size. Google haven't disclosed this limit but the below error will be shown when the content exceeds the maximum size:
Resource at url contents exceeded maximum size.
Google servers are not blocked by means of robots.txt or the user agent.
On W3C Markup Validator there are several tools to checkout is the resources had been properly marked up.
Regarding CSV check out Are there known services to validate CSV files
It's worth to note that the spreadsheet
should have enough room for the imported content; Google Sheets has a 10 million cell limit by spreadsheet, according to this post a columns limit of 18278, and a 50 thousand characters as cell content even as a value or formula.
it doesn't handle well large in-cell content; the "limit" depends on the user screen size and resolution as now it's possible to zoom in/out.

ImportXML is good for basic tasks, but it won't get you too far if you are serious in scraping:
The approach only works with the most basic websites (no SPAs rendered in browsers can be scraped this way. Any basic web scraping protection or connectivity issue breaks the process, and there isn't any control over HTTP request geo location, or number of retries) - and Yahoo Finance is not a simple website
If the target website data requires some cleanup post-processing, it's getting very complicated since you are now "programming with Excel formulas", rather a painful process compared to regular code writing in conventional programming languages
There isn't any proper launch and cache control, so the function can be triggered occasionally and if the HTTP request fails, cells will be populated with ERR! values
I recommend using proper tools (automation framework and scraping engine which can render JavaScript-powered websites) and use Google Sheets just for basic storage purposes:

I am trying to figure out whether it is possible to import latest parcel status from DPD.
For example, I would like to get 'Delivered' status from below link and import it to google sheets:
https://tracking.dpd.de/status/en_DE/parcel/05252044194808
Any attempts with importxml are, however, empty. Any chance there is a way to download the latest status to Google Sheets? Perhaps that site is secured from scrapping?
IMPORTXML and IMPORTHTML would return data whenever the web page information is not generated through JAVASCRIPT, disabling JAVASCRIPT on the web page you are trying to scrape data from shows no data, so most likely the whole content is generated through Javascript dynamically and that's the reason why those methods don't return any information.

I am trying to get texts from the Grammarly application imported into a Google spreadsheet using the IMPORTXML function. To do so, I follow the required syntax IMPORTXML(URL, xpath_query), but it keeps showing an error that the "imported content is empty".
However, the same steps work fine to import data from other websites, and I am confused what might be the matter with Grammarly. Is it because it does allow data scraping at all, maybe?
