Angular Grid: CSV Export

The grid data can be exported to CSV with an API call, or using the right-click context menu on the Grid.

What Gets Exported

The same data that is in the grid gets exported, but none of the GUI representation of the data will be. What this means is:

  • The raw values, and not the result of cell renderer will get used, meaning:

    • Value Getters will be used.
    • Cell Renderers will NOT be used.
    • Cell Formatters will NOT be used (use processCellCallback instead).
  • Cell styles are not exported.

  • If row grouping:

    • All data will be exported regardless of whether groups are open in the UI.
    • By default, group names will be in the format "-> Parent Name -> Child Name" (use processRowGroupCallback to change this).
    • Row group footers (groupIncludeFooter=true) will NOT be exported - this is a GUI addition only.

The CSV export will be enabled by default. If you want to disable it, you can set the property suppressCsvExport = true in your gridOptions.

Standard Export

The example below shows the default behaviour when exporting the grid's data to CSV.

Note the following:

  • You can use the Show CSV export content text button, to preview the output.
  • You can use the Download CSV export file button to download a csv file.
  • The file will be exported using the default name: export.csv.

Changing the column separator

By default, a CSV file separates its columns using ,. But this value token could be changed using the columnSeparator param.

Note the following:

  • You can use the select field at the top to switch the value of the columnSeparator param.
  • You can use the Show CSV export content text button, to preview the output.

Suppress Quotes

By default cell values are encoded according to CSV format rules: values are wrapped in double quotes, and any double quotes within the values are escaped, so my"value becomes "my""value". Pass true to insert the value into the CSV file without escaping. In this case it is your responsibility to ensure that no cells contain the columnSeparator character.

Note the following:

  • You can use the select field at the top to switch the value of the suppressQuotes param.
  • You can edit the cells to preview the results with different inputs.
  • You can use the Show CSV export content text button, to preview the output.
  • You can use the Download CSV export file button to download a csv file.

Prepending and Appending Content

The recommended way to prepend or append content, is by passing an array of CsvCell objects to appendContent or prependContent. This ensures that your content is correctly escaped.

For compatibility with earlier versions of the Grid you can also pass a string, which will be inserted into the CSV file without any processing. You are responsible for formatting the string according to the CSV standard.

Note the following:

  • You can use select fields at the top to switch the value of prependContent and appendContent.

    • With prependContent=CsvCell[][] or appendContent=CsvCell[][], custom content will be inserted containing commas and quotes. These commas and quotes will be visible when opened in Excel because they have been escaped properly.
    • With prependContent=string or appendContent=string, a string to be inserted into the CSV file without any processing, and without being affected by suppressQuotes and columnSeparator. It contains commas and quotes that will not be visible in Excel.
  • You can use the Show CSV export content text button, to preview the output.
  • You can use the Download CSV export file button to download a csv file.

Column Headers

In some situations, you could be interested in exporting only the grid data, without exporting the header cells. For this scenario, we provide the skipColumnGroupHeaders=true and skipColumnHeaders=true params.

Note the following:

  • Initially, grouped headers and header are exported.
  • Group Headers will be skipped if Skip Column Group Headers is checked.
  • Normal headers will be skipped if Skip Column Headers is checked.

Pinned Rows

If the pinned rows are not relevant to the data, they can be excluded from the export by using the skipPinnedTop=true and skipPinnedBottom=true params.

Note the following:

  • By default, all pinned rows are exported.
  • If Skip Pinned Top Rows is checked, the rows pinned at the top will be skipped.
  • If Skip Pinned Bottom Rows is checked, the rows pinned at the bottom will be skipped.

Hidden Columns

By default, hidden columns are not exported. If you would like all columns to be exported regardless of the current state of grid, use the allColumns=true params.

Note the following:

  • By default, only visible columns will be exported. The bronze, silver, and gold columns will not.
  • If Export All Columns is checked, the bronze, silver, and gold columns will be included in the export.

API

Grid Properties

suppressCsvExport
boolean
Prevents the user from exporting the grid to CSV.
Default: false

API Methods

exportDataAsCsv()
Function
Downloads a CSV export of the grid's data. See CSV Export.
function exportDataAsCsv(params: CsvExportParams): void;
getDataAsCsv()
Function
Similar to exportDataAsCsv, except returns the result as a string rather than download it. See CSV Export.
function getDataAsCsv(params: CsvExportParams): string;

Interfaces

CsvExportParams

columnSeparator
string
Delimiter to insert between cell values.
Default: ','
suppressQuotes
boolean
By default cell values are encoded according to CSV format rules: values are wrapped in double quotes, and any double quotes within the values are escaped, so my value becomes "my""value". Pass true to insert the value into the CSV file without escaping. In this case it is your responsibility to ensure that no cells contain the columnSeparator character.
Default: false
prependContent
string | CsvCell[][]
Content to put at the top of the file export. A 2D array of CsvCell objects (see Prepending and Appending Content section). Alternatively, you can pass a multi-line string that is simply appended to the top of the file content.
appendContent
string | CsvCell[][]
Content to put at the bottom of the file export. A 2D array of CsvCell objects (see Prepending and Appending Content section). Alternatively, you can pass a multi-line string that is simply appended to the bottom of the file content.
