Can the changes made by DQ for Excel directly update the connected data?

In Microsoft Excel, data can be connected to external data sources, and in certain circumstances, changes made in the Excel workbook can update the connected source directly.

This functionality is typically achieved through features like data connections, data queries, and data refresh options.

It’s important to note that the ability to update the connected source directly depends on the type of connection, the configuration settings, and the specific features used in Excel.

Not all data connections will behave in the same way, and you should carefully set up and manage your connections to ensure they meet your data synchronization requirements.

One specific use case where data synchronization is active is with Microsoft Dynamics 365 Business Central (formerly known as Dynamics NAV or Navision).

It does allow you to update data through Microsoft Excel. This is typically done using a feature called “Edit in Excel” or “Export to Excel.”

Can I connect my MS Excel Worksheet to external data sources to process data with the DQ for Excel Add-In?

Yes, MS Excel provides a wide range of options for connecting to various data sets.  Excel provides wizards and dialog boxes to guide you through the process of connecting to various data sources.

These wizards simplify the setup process.  You can use them to connect to various data sources, load the data into Excel for analysis, perform multiple data cleansing within DQ for Excel, and re-import i.e. push cleansed data back to the originating source.

Some of the common ways to connect MS Excel to import data from external data sources are shown below:

Import from Text/CSV: You can import data from text files or CSV (Comma-Separated Values) files by going to the “Data” tab and selecting “Get Data” or “Get External Data,” depending on your Excel version.

Import from a Database: Excel allows you to connect to various databases such as Microsoft SQL Server, MySQL, Oracle, and more. You can use the “Get Data” feature to establish a connection.

Import from Web: You can import data from websites and web services using the “From Web” option in the “Data” tab.

Connect to Cloud Services: Excel supports connecting to various cloud-based data sources like Microsoft Azure, SharePoint, OneDrive, Google Sheets, and more. You can sync data between Excel and these services.

Power Query: Power Query is a powerful tool in Excel for data transformation and import.

ODBC and OLEDB Connections: You can establish connections to databases and other data sources using ODBC (Open Database Connectivity) or OLEDB (Object Linking and Embedding Database) data connections.

API Integrations: Excel can connect to web-based APIs (Application Programming Interfaces) to fetch data in real-time.  This is often done using VBA (Visual Basic for Applications) macros or with the help of tools like

Linked Tables:
In Excel, you can create linked tables that are connected to external data sources. This allows you to refresh the data in your Excel workbook whenever the source data changes.

Power BI Integration:
If you have Microsoft Power BI, you can leverage its more advanced data connection and visualization capabilities and integrate it with Excel for more robust data analysis.

The method you choose will depend on the nature of the data source and your specific requirements.
Any of the methods you choose will allow you to process your customer data with ease using the DQ for Excel Add-In.

How do I process data exported for MS Dynamics CRM or D365 Sales/CE?

The process of data export and re-import in Dynamics 365 Sales/CE typically involves exporting data from the system, making changes or updates to the exported data, and then re-importing the modified data back into the system.

Here is a general overview of how the data export and re-import process typically works in Dynamics 365, or D365 Sales/CE:

Export your Customer Data: Export your selected data from Dynamics 365 Sales, such as Accounts, Contacts, Leads, or Opportunities.

Modify the data exported from Dynamics CRM or D365 Sales: Open the exported file in your chosen format (e.g., Excel or CSV).

Using DQ for Excel™: You can perform all necessary cleansing and formatting changes or updates to the data in the file, whilst ensuring you follow any data formatting guidelines to prevent import errors.  Note: You will need to overwrite the existing data for updates to process upon data re-import.

Save the Modified Data:
After making the required changes, save the file in the same format (e.g., Excel or CSV) without changing the file structure.

Re-Import Data: Start the import process by selecting the modified data file you saved earlier.

Complete the Import: Once the import is successful, verify that the cleansed data imported appears correctly in Dynamics 365 Sales.

Validation and Cleanup: After importing, it’s essential to confirm that the cleansed data is accurate and complete.

Please refer to the official Microsoft Dynamics CRM or D365 Sales documentation or seek assistance from Microsoft support for the most up-to-date information and guidance on data export and re-import processes.

Using this approach, it is very simple to cleanse and update your D365 Sales data on a regular basis without the need for I.T. Support.

If in doubt speak to your D365 Sales system administrator.

Can D365 Business Central (BC) data be updated by the DQ for Excel Add-In?

Yes, Microsoft Dynamics 365 Business Central (formerly known as Dynamics NAV or Navision) does allow you to update data through Microsoft Excel.

This is typically done using a feature called “Edit in Excel” or “Export to Excel.”

You can export data from Business Central to an Excel spreadsheet using the Edit in Excel setting.  It is then actively connected so that any bulk changes made in a workbook will update directly into D365 BC.

This means customer and vendor data can be updated automatically with cleansed data in minutes and no export and re-import are required.

Using this approach, it is very simple to cleanse and update your D365 BC data on a regular basis without the need for I.T. Support.

If in doubt speak to your D365 BC system administrator.

What is address verification and why is it important?

Address verification is a process used to confirm the accuracy and validity of a physical address to ensure that the address provided by an individual or business is real and can receive post (mail) or shipments (parcels).

It is important for several reasons, including: preventing fraud, ensuring accurate delivery of physical mail and packages, and complying with legal and regulatory requirements.
