Setting Up the Template
Introduction
Note |
---|
This is Part 2 of the three-part tutorial series Financial Report scenario. It is recommended that you complete Part 1 - Using Modifiers and Ordinal Syntax before starting this section. This tutorial also assumes a basic understanding of how ExcelTemplate imports data how that affects formulas and formatting. |
Info | ||
---|---|---|
| ||
In the downloadable TODO ADD FILE REFERENCE ExcelWriter_Basic_Tutorials.zip, there is a completed template file located in CompleteFinancialReport/templates/Part2_Financial_Template.xlsx. A copy of the completed template file is also available TODO ADD FILE REFERENCE. |
Getting Started
In this tutorial ExcelTemplate is being used to populate data in a template set up with styles and formats. This part of the tutorial uses formulas and persists Excel styles.
Note |
---|
This example assumes an understanding of ExcelTemplate. If you are not familiar with how to set up an Excel template with data markers, please go through the Simple Expense Summary first. |
Data Sheets
This sub-report makes use of a data sheet. This is where the data markers will go. It should look something like this:
The alternating rows (highlighting added for demonstration) contain sum formulas, visible in the function bar below:
The sum formula is a standard Excel function. When the data is populated, the A1:A1 reference gets updated to include all the data. The result should be something like this (highlighting added for demonstration):
Referencing the Data Sheet
The next step is adding references to the data sheet. This example references the "SUM" formulas on the data sheet. These sums are added to a percent change equation. This will result in a template resembling the following:
Note the formula in the formula bar, "Sheet2" is the data sheet.
Info | ||
---|---|---|
| ||
In this example, the sum rows alternate on the data sheet. If you stretch a formula, you'll have to update the references to skip every other row. |
1. Select C4 on Sheet1.
2. Start to type the formula by entering =(
3. Click over to Sheet2, Row 2 and select the second SUM cell. (B2 in this example)
4. Go back to Sheet1 and add a minus sign for =(Sheet2!B2-
5. Click over to Sheet2, Row 2 again and select the first SUM cell.
...
Setting Up the Template
The goal of this part of the tutorial is how to apply number formats and conditional formatting to ExcelTemplate files and what you can expect as ExcelTemplate imports data.
The final template will look like this:
The bottom of the worksheet has a section for the data that will be imported. Each section has a total row summing all of the values for the section. This formula will expand as ExcelTemplate imports data.
At the top is a grid that calculates the percent in change between each quarter, based on the asset, loss, and other totals. The formulas are set up as "=(Sheet2!B2-Sheet2!A2)/(Sheet2!A2)
7. Drag this formula Horizontally only because of the alternating rows.
8. Repeat with rows 4 and 6
Number Formats
The value returned by the percent change equation should be displayed as a percentage. The table cells all have to be formatted.
1. Select all cells"
for each cell in the grid.
Number Formats
This section will cover how to add number formatting and the expected behavior for ExcelTemplate as it imports data.
1. Select the 9 cells in the percentage grid at the top of the worksheet (C4:E6).
2. Right click and select "Format Cells..."
3. Select "Percentage" on the Number tab.
Setting Styles
The next step is setting up the table. Add a header and label the rows and columns to end up with a complete table:
Once the table is complete, add styles.
1.Select "Percent Change by Quarter" and set it to "Heading 1." Heading 1 is found in the named styles list, on the "Home" tab of the ribbon.
2. Select the header row (B3:E3) and set it to "Total" in the named styles menu.
3. Select the row labels (B4:B6) and set that to "Total."
You should now have this:
4. Select the area of B3:E6, and apply a consistent border:
5. Now select B2:E2 and apply a bottom border in dark blue.
The final template should look like this:
4. Click OK
5. Select cells C12:F12, C17:F17, and C22:D22.
6. In the top tool bar, under the 'Number' tab, click the "$" to apply the currency format.
So far the number formats have been applied to cells that only contain formulas, but number formats also work with cells that contain data markers.
1. Select cells C11:F11, C16:F16, C21:F21.
2. At the top bar, click the "$" to apply the currency format.
As ExcelTemplate populates the worksheet, the number format will be copied to all the new rows of data that are inserted where the data markers are.
Conditional Formatting
ExcelTemplate will preserve existing conditional formatting. If the conditional format includes a formula, that formula will also be updated as new rows are inserted into the file.
In this case, the conditional formatting will be applied to the 'percent table' and it format negative numbers to be bold and red.
1. On the "Home" tab in Excel, click on "Conditional Formatting"
2. Select "New Rule..."
3. In this tutorial the condition type is "Format only cells that contain..." The rule is "Cell value less than 0"
4. Click on "Format..." Set the text to be dark red. Set the typeface to be bold.
5. Click OK to save the rule.
Adding an ExcelWriter Reference in Visual Studio
Info | ||
---|---|---|
| ||
In the sample code, the reference to SoftArtisans.OfficeWriter.ExcelWriter.dll has already been added to the CompleteFinancialReport project. |
...
- Open Visual Studio and create a .NET project.
- The sample code uses a web application.
- Add a reference to SoftArtisans.OfficeWriter.ExcelWriter.dll
- SoftArtisans.OfficeWriter.ExcelWriter.dll is located under Program Files > SoftArtisans > OfficeWriter > dotnet > bin
Writing the Code
1. Include the SoftArtisans.OfficeWriter.ExcelWriter namespace in the code behind
Code Block |
---|
using SoftArtisans.OfficeWriter.ExcelWriter;
|
...
3. Open the template file with the ExcelTemplate.Open
method.
Code Block |
---|
XLT.Open(Page.MapPath("//templates//Part2_Financial_Template.xlsx"));
|
4. Create a DataBindingProperties
object. None of the binding properties will be changed for this tutorial, but DataBindingProperties
is a required parameter in ExcelTemplate
data binding methods.
Code Block |
---|
DataBindingProperties dataProps = XLT.CreateDataBindingProperties();
|
Data Binding
1.Get the data for the Assets, Losses, and Other datasets
Info | ||
---|---|---|
| ||
In the sample projectSimilarly to part 1, we are parsing CSV files with query results, rather than querying a live database. The CSV files are available under the data directory. There is a copy of the CSV parser, |
1.Get the data for the Assets, Losses, and Other datasets
These calls are to a helper method GetCSVData
that parses the CSV files and returns a DataTable
with the values.
If you are following in your own project and would like to parse the CSV files as well, you will need to:
...
Code Block |
---|
...
...
Code Block |
---|
DataTable dtAssets = GetCSVData("//data//Assets.csv");
DataTable dtLosses = GetCSVData("//data//Losses.csv");
DataTable dtOther = GetCSVData("//data//Other.csv");
|
2. Use ExcelTemplate.BindData
to bind the data for the Assets, Losses, and Other data sets.
Code Block |
---|
XLT.BindData(dtAssets, "Assets", bindingProps);
XLT.BindData(dtLosses, "Losses", bindingProps);
XLT.BindData(dtOther, "Other", bindingProps);
|
3. Call ExcelTemplate.Process() to import all data into the file.
Code Block |
---|
XLT.Process();
|
4. Call ExcelTemplate.Save() to save the final file.
Code Block |
---|
XLT.Save(Page.Response, "temp.xlsx", false);
|
The final output should look something like this:
Final Code
Code Block |
---|
using SoftArtisans.OfficeWriter.ExcelWriter;
...
//Instantiate the template object
ExcelTemplate XLT = new ExcelTemplate();
//Open the file
XLT.Open(Page.MapPath("//templates//Part1_Financial_Template.xlsx"));
//Create data binding properties
DataBindingProperties bindingProps = XLT.CreateDataBindingProperties();
//Get the data from the CSVs. More info about the generic parser is available
//in the project and in the tutorial above.
DataTable dtAssets = GetCSVData("//data//Assets.csv");
DataTable dtLosses = GetCSVData("//data//Losses.csv");
DataTable dtOther = GetCSVData("//data//Other.csv");
//Bind each datatable
XLT.BindData(dtAssets, "Assets", bindingProps);
XLT.BindData(dtLosses, "Losses", bindingProps);
XLT.BindData(dtOther, "Other", bindingProps);
//Call process to import data to file
XLT.Process();
//Call save
XLT.Save(Page.Response, "temp.xlsx", false);
