Description
This operator can be used to load data from Microsoft Excel spreadsheets. This operator is able to read data from Excel 95, 97, 2000, XP, and 2003. The user has to define which of the spreadsheets in the workbook should be used as data table. The table must have a format such that each row is an example and each column represents an attribute. Please note that the first row of the Excel sheet might be used for attribute names which can be indicated by a parameter. The data table can be placed anywhere on the sheet and can contain arbitrary formatting instructions, empty rows and empty columns. Missing data values in Excel should be indicated by empty cells or by cells containing only '?'.
For complete understanding of this operator read the parameters section. How to change text in a word label template for mac. The easiest and shortest way to import an Excel file is to use the import configuration wizard from the Parameters panel. The best way, which may require some extra effort, is to first set all the parameters in the Parameters panel and then use the wizard. Please make sure that the Excel file is read correctly before building a process using it.

Tutorial ProcessesReading an ExampleSet from an Excel file
For this Example Process you need an Excel file first. The one of this Example Process was created by copying the 'Golf' data set present in the Repositories into a new Excel file which was named 'golf'. The data set was copied on sheet 1 of the Excel file thus the sheet number parameter is given value 1. Make sure that you provide the correct location of the file in the Excel file parameter. The first cell of the sheet is A1 and last required cell is E15, thus the imported cell range parameter is provided value 'A1:E15'. As the first row of the sheet contains names of attributes, the first row as names parameter is checked. The remaining parameters were used with default values. Run the process, you will see almost the same results as you would have gotten from using the Retrieve operator to retrieve the 'Golf' data set from the Repository. You will see a difference in the meta data though, for example here the types and roles of attributes are different from those in the 'Golf' data set. You can change the role and type of attributes using the data set meta data information parameter. https://brokerstree754.weebly.com/blog/download-facebook-for-mac-mini. It is always good to make sure that all attributes are of desired role and type. In this example one important change that you would like to make is to change the role of the Play attribute. Its role should be changed to label if you want to use any classification operators on this data set.
