After export of the yammer notes (by verified administrator), how to bulk import them again if needed - to another network/group - with names, labels and content (preferably, interlinked)?
It isn't possible to do this as there isn't a supported API available for notes. The purpose of the data export is provide access to data in a raw format which can be supported by eDiscovery tools, but re-importing content isn't a supported scenario. There is a message API for Yammer, but even this isn't designed to support import of content exported from another network since there is no way to back date the content.

Slack exports its data as a ZIP, without images.
It uses public URLs instead, so on my imported chanels inside Rocket, I see only links to slack instead of the inline images.
Is there any way to instruct Rocket to automatically download all those images and embed them in the channels?
What would be the best way to do that?
Currently, RocketChat cannot automatically download and import the Slack attachments. There are several 3rd party and open source tools to separately download the referenced attachments in the Slack export files. One example is slack-advanced-exporter.
Then, you have all the attachments in a separate folder. This is still not enough to import the Slack messages with the attachments into RocketChat. An additional converter would be helpful to replace the urls in the Slack JSONs with the correct file links and create the correct folder structure for the attachments. As far as I know, this additional converter is still missing (at least in the open source landscape).
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'
Tl;Dr
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.

One answer suggest the use of an API and Google Apps Script
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:

We used to use Yammer a while back and now we're getting back on it. Problem is that most people who used it previously have left and the content left over is irrelevant today. Is there a way through an API or something to delete all content and posts on our Yammer network?
Your help is appreciated.
There are APIs which will let you delete messages (https://developer.yammer.com/docs/messagesid), but customers tend to just start using Yammer again. The old content disappears off the bottom. In many cases there are nuggets of info that get turned in up searches later which prove to be useful. if you want additional API help it may be best to open Support Requests with Microsoft for assistance. The main support site is available, but you can open requests through the O365 Admin Portal.
A bit old but still a relevant question. My organisation wanted to do this and the advice from Microsoft Premier support was:
Verified admin can choose to use the "Remove users" option under Network Admin portal. The option of "Permanently remove this user and messages" lets you remove the user and all the messages they posted (*note: This cannot be reversed).
As an alternative, for bulk deletion, the Bulk update feature, data export along with the Rest API endpoints should help achieve this. And before starting to delete the content ensure to set the data retention policy as "Hard Delete".
• For deleting the users/files/messages/notes, use the export files' (messages.csv, files.csv and Pages.csv) which have the API URLs in it which can be called from within a powershell script for example. One will have to format and make a post request through powershell. Herewith I attached an sample script just for your reference.
(it is regarding user deletion but similar call applies)
messages.csv api_url https://developer.yammer.com/docs/messagesid
files.csv file_api_url https://developer.yammer.com/docs/uploaded_filesid
Pages.csv page_api_url https://developer.yammer.com/docs/uploaded_notesid
• For managing and removing yammer users – you could delete the users using bulk update feature.
You could get users list by performing an export: Network Admin > Export Users and Export all users. Then perform a "Bulk Update Users" with the above spreadsheet saved as a .csv file. Note that you'll need two columns in this spreadsheet. The first should be titled 'Action' and the second should be titled 'Email Address' (both without the quotes). Under action, you'll want to put 'Suspend' on every line and you'll have your users' email addresses from step 6 under 'Email Address'.
Go to Network Admin > Bulk Update Users and import that .csv file there (there's a sample Bulk Update file for reference at the page itself – it has more columns than you'll need, so just pay attention to the first two).
We can export parse.com database data as JSON, but how can you export pictures stored there together with text data?
I was looking at the settings and couldn't find anything what would help with that.
There is no way to do it automatically via an export button, however it is fairly easy to do manually.
You'll want to iterate through your table and pull down each item individually via the ParseFile interface.
Depending on what platform you are using, you could use the OSX or C# APIs. Or just go with using Python.
I would like to use the GSA API to read and write the Dynamic Navigation settings. From the API documentation, it looks like this isn't possible. Screen scraping is another option, but most of the page content is built client-side with JavaScript, which makes normal command-line screen scraping very difficult.
Is there an undocumented feature of the API perhaps, or some other way to access settings that aren't covered in the API?
The unofficial gsa-admin-toolkit project has a gsa_admin.py script which can import and export configuration files, and, most importantly, re-sign them. Before, editing an exported config file wasn't an option because they contain a checksum or hash. They get corrupted when edited.
This tool allows editing of the config file, re-signing, and importing back to the GSA.
