Transforming Excel data can be a complex task this article describes how Advanced ETL Processor works with Excel data.
Reading Excel data
Data can be extracted from entire Sheet or just from the data range.
Advanced ETL Processor assumes that "Sheet name" and "Range name" a delimited by dot.
Users can still call Sheets as a "Great.Victory"
The logic as follows:
Advanced ETL Processor will check if Great.Victory sheet exits than it will read it
If it does not exists it will check if Great sheet exits
If it does exists it will check if Victory range exists if it does It will read data from just Victory range
If it does not it will read the data from Sheet "Great"
Please make sure that the range names are not duplicated with in the file
Writing Excel data
Advanced ETL Processor gives the user various options to generate Excel files.
Creating new file
| Sheet Name | Create new file? | Add data starting from | Sheet Exists? | Range Exists? | Notes |
|---|---|---|---|---|---|
| SheetName | Yes | Top | No | No | New file is created with the Sheet called "SheetName", data is inserted from the top left corner |
| SheetName |
Yes |
Cell |
No |
No |
New file is created with the Sheet called "SheetName", data is inserted from the Cell |
| SheetName | Yes |
Last Row |
No |
No |
New file is created with the Sheet called "SheetName", data is inserted from the top left corner |
| SheetName.RangeName |
Yes | Top | No | No | New file is created with the Sheet called "SheetName", data is inserted from the top left corner, new range called "RangeName" is created with the size equlal to the populated data |
| SheetName.RangeName | Yes | Cell | No | No | New file is created with the Sheet called "SheetName", data is inserted from the Cell, new range called "RangeName" is created with the size equlal to the populated data |
| SheetName.RangeName | Yes | Last Row | No | No | New file is created with the Sheet called "SheetName", data is inserted from the top left corner, new range called "RangeName" is created with the size equlal to the populated data |
Adding/ updating data in the existing Excel file
| Sheet Name | Create new file? | Add data starting from | Sheet Exists? | Range Exists? | Notes |
|---|---|---|---|---|---|
| SheetName | No | Top | No | No | New Sheet is created called "SheetName", data is inserted from the top left corner |
| SheetName |
No | Cell |
No |
No |
New Sheet is created called "SheetName", data is inserted from the Cell |
| SheetName | No | Last Row |
No |
No |
New Sheet is created "SheetName", data is inserted from the top left corner |
| SheetName.RangeName |
No | Top | No | No | New Sheet is created "SheetName", data is inserted from the top left corner, new range called "RangeName" is created with the size equal to the the size of populated data |
| SheetName.RangeName | No | Cell | No | No | New Sheet is created "SheetName", data is inserted from the Cell, new range called "RangeName" is created with the size equal to the the size of populated data |
| SheetName.RangeName | No | Last Row | No | No | New Sheet is created "SheetName", data is inserted from the top left corner, new range called "RangeName" is created with the size equal to the the size of populated data |
| SheetName | No | Top | Yes | No | Within Sheet "SheetName", data is replaced starting from the top left corner, the rest of the data within Sheet is left intact. |
| SheetName | No | Cell | Yes | No | Within Sheet "SheetName", data is replaced starting from the cell, the rest of the data within Sheet is left intact |
| SheetName | No | Last Row | Yes | No | Within Sheet "SheetName", data is is inserted starting from the last empty row, the rest of the data within Sheet is left intact. |
| SheetName.RangeName | No | Top | Yes | No | Within Sheet "SheetName", data is replaced starting from the top left corner, the rest of the data within Sheet is left intact, than new range called "RangeName" is created with the size equlal to the the size of populated data |
| SheetName.RangeName | No | Cell | Yes | No | Within Sheet "SheetName", data is replaced starting from the cell, the rest of the data within Sheet is left intact, than new range called "RangeName" is created with the size equlal to the the size of populated data. |
| SheetName.RangeName | No | Last Row | Yes | No | Within Sheet "SheetName", data is is inserted starting from the last empty row, the rest of the data within Sheet is left intact, than new range called "RangeName" is created with the size equlal to the the size of populated data. |
| SheetName.RangeName | No | Top | Yes | Yes | Within Sheet "SheetName", data is replaced starting from the top left corner of the range "RangeName", the rest of the data within Sheet is left intact, than range "RangeName" size is set to the the size of newly populated data. |
| SheetName.RangeName | No | Cell | Yes | Yes | Within Sheet "SheetName", data is replaced starting from the cell, the rest of the data within Sheet is left intact, than range "RangeName" size is set to the the size of newly populated data. |
| SheetName.RangeName | No | Last Row | Yes | Yes | Within Sheet "SheetName", data is is inserted starting from the last row of the range "RangeName" +1, the rest of the data within Sheet is left intact, than range "RangeName" size increased by the size of newly populated data |
