Try SpreadJS’s spreadsheet components. Then add a script to the page that initializes the Spread. Sheets component, and a div element to contain it since the SpreadJS spreadsheet component utilizes a canvas, this is necessary to initialize the component:. We need to create an instance of the client-side ExcelIO component that we can use to actually open the file:.
Then we need to add a function to import a file. In this example, we import a local file, but you can do the same thing with a file on a server. The following is an example of an input element where the user can enter the location of the file:.
The following code for the import function just uses a local file for the “excelUrl” variable:. Now we can use Spread. Sheets script to add another revenue line into this file. We can write a function for the click event handler for that button to add a row and copy the style from the previous row in preparation for adding some data.
To copy the style, we will need to use the copyTo function and pass in:.

All of the following script code for adding data and a Sparkline will be contained within this button click event handler. For most of the data, we can use the setValue function. This allows us to set a value in a sheet in Spread by passing in a row index, column index, and value:.
Lastly, we can copy the formulas from the previous rows to the new row jquerh columns R through AD using the copyTo function again, this time using CopyToOptions. Now we can add a sparkline to match the other rows of data. To do this, we need to provide a range of cells to get the data from and some settings for the sparkline. In this case, we can specify:.
If you were to try running the code now, it might seem a little slow because the workbook is repainting every time data is changed and styles are added.
To drastically speed it up and increase performance, Spread.
Sheets provides the ability to suspend painting and the calculation service. Once we add that code, we can open the page in a web browser and see the Excel file load into Spread.
Sheets with an added revenue row. Alternatively, if you load a file from a website URL, it should open fine in any browser. Finally, we can add a button to export the file with the added row. To do this, we can use the client-side ExcelIO code built into Spread. That code gets the export file name from an exportFileName input element.
We can define it and let users name the file like so:. Once you add a revenue row, you can export the file using the Export File button. Make sure to add the FileSaver external library to allow users to save the file expory they want:.
When the file is successfully exported, you can open it in Excel and see that the file looks like it did when it was imported, except there is now an extra revenue line that we added.
