Encountering issues with AngularJS number filter when integrating it with UI grid

When using the angularjs number filter in angular-ui-grid, I am facing an issue. The filter works perfectly fine within the grid, but when I export the grid to csv and open it in Excel, the formatting is not maintained.

I have included the filter in the exporterFieldCallback as well.

Within the grid: 

cellFilter: 'number:6', type: 'number'
. And in the exporterFieldCallback:

if(col.name == 'columnName'){                   
                    return $filter('number')(input,6);
                }

The numbers are displayed with 6 decimal places in the grid. However, once exported to csv and opened in Excel, the zeros are truncated.

You can view a demo of the angularjs number filter here, where the specified fractionSize displays correctly within the grid but not after export.

For example, if a value in the grid is 3.000000, Excel only shows 3. If the value is 1.415400 in the grid, Excel truncates it to 1.4154.

Why are the zeros getting truncated when exporting angular-ui-grid to csv and opening it in Excel? How can I ensure that values display consistently between the grid and Excel?

Answer №1

It seems like the issue you're facing is more related to Excel than AngularJS.

When CSV files are opened in Excel, it tends to manipulate numbers by removing leading and trailing zeros. To verify if your CSV file is accurate, try opening it in a text editor to check for any missing zeros.

If you frequently import data into Excel, there are various solutions available. However, if all you need is values to display up to 6 decimal places, a simple option would be to import the data first and then adjust the formatting using the Increase Decimal feature within Excel: https://i.stack.imgur.com/EACdN.png
