Facebook has removed API access for almost every reasearch software on September 5, 2019. Please take look at this post.
This seems to be a bug, we need to solve. Upgrading to NodeXL Pro will not solve the issue.
Thank you for pointing this out.
This seems to be a rare problem. Please request NodeXL Tech Support on this page.
NodeXL can be installed on Windows operating systems only. Mac users need to install a Virtual Machine. Please take a look at this page.May 27, 2020 at 4:52 am in reply to: [COMException]: PivotFields method of PivotTable class failed #8974
This feature is invoked during the creation of the Time Series analysis spreadsheet. Pivot Tables appeared in Office 2010 and later.
If you are using Office 2007 you can turn this off in NodeXL> Graph> Automate> Time Series (uncheck).
Also please check if your settings are correct under NodeXL> Analysis> Graph Metrics> Time Series.
If you cannot solve the problem, feel free to request Tech Support on this page.

An antivirus software or firewall is blocking NodeXL from downloading the required files.
Solution 1: Add an exception for http://www.nodexlgraphgallery.org to your antivirus/firewall.
Solution 2: Try a different internet connection.
If you run into any other issue, please have a look at this page: https://www.smrfoundation.org/nodexl/installation/
The second option adds the edge type “Follows” to the Edges worksheet in your dataset. It will get the followers from all users that are detected in your search query. The API will usually return the most recent followers first.
This option can easily max out the capacities of NodeXL and Excel. And it will take a long time to download the data. You can of course limit the number of followers to be collected, but still you might end up with more than a million edges e.g. if there are 1000 users in your network with an average of 1000 followers. That is way too much to handle for NodeXL.
There may be special use cases for this option, e.g. download data, export as .gexf and then analyze in Gephi. But we generally recommend to not use this option.
The search operators “from: and “until:” only work within the time frame of the past 9-10 days before the date of your query.
Because of the Twitter Public API restrictions, you will not get any tweets beyond this time limit.
If you are looking for historical Twitter data, you need access to a different API which NodeXL does not provide. Here is a good article about that topic: https://gwu-libraries.github.io/sfm-ui/posts/2017-09-14-twitter-data
It is possible that the network you are trying to analyze is too big to process with the clustering algorithm.
Please send your dataset to firstname.lastname@example.org and we will take a look.
Currently, the NodeXL Search Network importer only connects to the free Twitter Search API.
Upgrading your Twitter account will not help to get more data via the importer. We are currently exploring the integration of Twitter Premium data with a new importer.
We also have a data collection service in place. Please contact us at email@example.com to start your own data collection plan.

Depending on the size of the list, the download of followers will take a while. Keep in mind that downloading more than 1 million edges (followers) will max out the capabilities of Excel. Therefore it might be a good choice to “Limit friends and followers per user”.
Make sure to uncheck the box “Import only the Twitter users I’m interested in”. Otherwise, the network generator will look only for edges between the users in the list.
When looking at follower data, we also suggest to limit the download of tweets per user to 1. This will speed up the process.June 18, 2019 at 6:17 am in reply to: [OutOfMemoryException] error type 'System.OutOfMemoryException' #8395
