How to show an excel button that allows the users to download the results in tableau

I want to show an excel button that allows the users to download the results.
I want the users to download the table data shown in the workbook. The user should be able to download the filtered data.
For example if he selects regions as 'America', then in the excel sheet he must get only the data having 'America' as the region.
Please help me in achieving this!
The short answer is that you can't.
Unfortunately, there's not Excel download button like download PDF for the moment.
The long answer is about two workarounds that you can follow:
if you're using Tableau Server you can simply add .csv to your view's URL to make it downloadable in CSV. For example http://tableauservercompany/#/myview will become http://tableauservercompany/#/myview.csv. You can also apply filters as described in this tutorial.
another workaround is to include in your workbook a worksheet (not a dashboard) with the table you want to let users download to Excel. In this way users can go to Download and select Excel file.
Once your dashboard is complete, just drag the download component (lower left corner in Object section), and set it for cross-tab (default is PDF).
This feature will be available if your dashboard is published on Tableau Server/Online and it will download the current data depending of what users see when they click on the download button.

IBM Db2 on Cloud: Results not shown in SQL editor

So I am unable to verify if the results are correct.
How do I go about it?

Click on the arrow on the right. It will open a new window and display the result.

Exporting Data from Access into a CSV File for Use in MongoDB

I need to recreate a database in a MongoDB backend environment that's currently in Microsoft Access format. Please note: I am not very familiar with MS Access. When I open up the db in question and click on "External Data" I see options to:
1.) "Import the source data into a new table in the current database" -- I clearly don't want this, and
2.) "Link to the data source by creating a linked table". I don't think I want this either.
I assume what I need is to download a version of this db as a CSV file. From there I can write an ETL to get the data into a mongo collection.
How do I do this from within Access? Is there an option to simply download the data onto my local computer in something like CSV format?
When I open up the db in question and click on "External Data" I see
options to:
You will also se icons with small arrows for export to Excel or text files - which, that latter, is what you are after.

pgAdmin4 import/export option greyed out

so I recently configured and started using Pgadmin 4, managed to set up my localhost database, and my querys work properly, but for some reason I can't use the import/export dialog when I want to export my data as CSV, as it shows as greyed out. Could anyone help me out please? Image for Reference.
EDIT: The "Download as CSV (F8)" button is not working either.
You can just right click the table and use Import/Export option.
OR
To make Import/Export option you need to select table then click on Tools => Import/Export
And CSV download button is not working on some platform in current version that's a bug and already reported, It'll be fixed in next release.
if you are looking to export the query results , you need to do copy
COPY ([Query]) TO '[File Name]' DELIMITER ',' CSV HEADER;
Make sure you have created the file and it has all permissions to access
