This is a guide on how to connect an Excel sheet to a Steem Blockchain SQL Server and link Charts and pivot tables to it or create a control Dashboard
Delegating Steem Power is likely to be widely used in the next future so it may become useful a tool for tracking it with the report and data management functionalities of an Excel workbook
In a few steps we will create a tool that gets delegation history and current delegation account state from the blockchain
it is possible to change the SQL query accessing Excel objects acording to the input parameters from a range of cells in Excel
This animations below ,shows a tool to gets delegation history for given delegator and delegatees ,it also filter the historic data to show a snapshot of live delegations in real time
You are welcome to give it a try from : https://github.com/Devba/StemmDelegatingWorksheet
Steps for creating a Excel linked to the Steem blockchain
1 - Create a data source connected to the SQL server
W have to create a new data connection in Excel , the steps for this may vary depending on Excel version , but the important is to select an SQL Server type connection
Then enter the following parameters when required
There is a great tutorial for this step , check it if you are struggling with the connectiion :https://steemit.com/steemit/@arcange/steemsql-com-how-to-create-a-steem-analytic-report-with-microsoft-excel>
One tip to avoid downloading a whole table which could slow down the queries is to the connection properties dialog and change the following parameters
something like this
2-Create the user interface
We can use excel ranges asr input parameters , then we will insert to buttons which we will link to the code below
We can use excel ranges asr input parameters
I inserted two button shapes and then set them to run macros
The result data feeds a table Excel object , so we can use filtering , ordering, etc.... as well as creating pivot tables and charts
3-Set parameters to query database on works
Sorry this section is still on works

4-Change SQL from Excel macros
This is the code which updates sql to query de database ,its inputs are 2 excel cells
We just need a few lines to launch the query and update the charts
Get Excel sample and source code
