By the end of this chapter you will be able to:

• Collect data from additional tabs in excel spreadsheets

A file containing a mapping of Counties to Regions can be found in the input files, at:
…

In 2 Using Excel Templates, you downloaded train.zip and saved the files to <path>. Find this file: <path>\inputData\AccountTransactions\AccountTransactions.xlsx
On the . The second tab of this workbook – accountHistory – details for the accounts are provided. You will create a file collector to read in this information: accountHistory contains details of account transactions.  

Upload data from using a file collector

You have already learned how to upload data using a file collector in 3 Combining Data Sets. By default the file collector reads from the first sheet in the workbook. The stream that PhixFlow creates when you upload the data is configured to hold this data. For this exercise, you need the data from the second worksheet. You will need to set additional options to configure PhixFlow to use this sheet.

The easiest way to do this is to load the data from the first sheet, then edit the collector properties.

1. Create a new model called Read Account History

...

By default the file collector is set up to read from the first sheet in the workbook – and the stream is configured to hold this data.
You will need to update this configuration to read from the second sheet:

...

• Right click on the stream and select Permanently Delete

PhixFlow displays the empty model in the modelling pane on the left and opens the model property tab on the right. In Basic Settings →  Name, enter Read Account History.

   


2. Add a file collector and set Basic Settings → Name: LoadAccountHistory.

   Expand
   title How?
   From the model toolbar, drag a  Insert excerpt _file_collector _file_collector nopanel true  into the model. PhixFlow displays the property tab for the new file collector.

   
   

3. In the property tab toolbar, click 

   Insert excerpt
   _save _save nopanel true

   In the model, hover your mouse pointer over the AccountHistory file collector to display the context toolbar and click  Insert excerpt _upload_file _upload_file nopanel true .  Navigate to the directory <path>\train\inputData\AccountTransactions\AccountTransactions.xlsx. Select the file AccountTransactions.xlsx and click Open, then click Insert excerpt _upload_button _upload_button nopanel true .

   
   

5. PhixFlow adds a new stream to the model, called LoadAccountHistory.

Change the file collector to load the second worksheet

...

1. In the model, right-click the new stream and click permenantly delete
2. Double-click LoadAccountHistory to open its property tab. Set Advanced → Excel Data Range Expression: "accountHistory!A1:F100"

...

1. In the File Columns section

...

1. , delete the column information that PhixFlow has already loaded.
2. Click Image Added - Create  file attributes 
3. PhixFlow already knows about the data in the spreadsheet. It now uses the expression you added to read the information about the columns in the second worksheet. PhixFlow adds the attributes to the list.
4. In the model view, from the hover menu of the file collector

...

1. press Image Added - Create a new Stream

...

2. Save your changes
3. Have a look the attributes in the new stream – you can see that these have been derived from the columns in the file collector

...

2. Run analysis on the stream and confirm that the data that has been read into PhixFlow is from the second tab in the spreadsheet
