GravityExport Lite for Gravity Forms

Sure, makes sense. You can override the label hooking into
gfexcel_field_label, gfexcel_field_label_{type}, gfexcel_field_label_{type}_{form_id} or
gfexcel_field_label_{type}{form_id}{field_id}

The field object is provided as parameter, so you can check for type and stuff programmatically.

You can override the value by hooking into gfexcel_field_value, gfexcel_field_value_{type},
gfexcel_field_value_{type}_{form_id} or gfexcel_field_value_{type}_{form_id}_{field_id}

The entry array is provided as a parameter, so you can combine fields if you want.

Great question! Yes you can! You can set it on the settings page, or make use of the following hooks to get that working:
gfexcel_field_separated_{type}{form_id}{field_id} where every variable is optional.

Yes it can, in multiple ways:

The default way the plugins renders output is by calling get_value_export on the field.
All Gravity Forms fields need that function, so make sure that is implemented.
The result is one column with the output combined to one cell per row.

But you can also make your own field renderer, like this:

1. Make a class that extends GFExcel\Field\BaseField (recommended) or extends GFExcel\Field\AbstractField or implements GFExcel\Field\FieldInterface
2. Return your needed columns and cells by implementing getColumns and getCells. (See AddressField for some inspiration)
3. Add your class via the gfexcel_transformer_fields hook as: type => Fully Qualified Classname (e.g., $fields['awesome-type'] => 'MyTheme\Field\MyAwesomeField')

By now you really should know you can change almost every aspect of this plugin. Don’t like the name?
Change it using the settings page, or by using the gfexcel_renderer_filename or gfexcel_renderer_filename_{form_id} hooks.

Also you can update title, subject and description metadata of the document by using
gfexcel_renderer_title({form_id}), gfexcel_renderer_subject(_{form_id}) and
gfexcel_renderer_description({form_id}).

Sure, why not. By default, we sort on date of entry in ascending order. You can change this, per form,
on the Form settings page (GravityExport Lite) under “General settings”.

You’re in luck: for those situations we’ve added a bulk option on the forms table.
As a bonus, you can select multiple forms, and it will download all results in one file,
on multiple worksheets (!!!)

You can disable the hyperlinks by using the gfexcel_renderer_disable_hyperlinks-hook.

//add this to your functions.php add_filter('gfexcel_renderer_disable_hyperlinks','__return_true'); 

A number field is formatted as a number, but most fields default to a string.
As of this moment, there are 3 field types. Boolean,String and Numeric. You can set these per field.

//add this to your functions.php use GFExcel\Values\BaseValue;  add_filter('gfexcel_value_type',function($type, $field) {     if($field->formId == 1 && $field->id == 2) {         //Possible values are 'bool', 'string' or 'numeric',         //or, use the constant, preferred:         return BaseValue::TYPE_NUMERIC; //TYPE_STRING, TYPE_BOOL     } }, 10, 2); 

Since most values are Value Objects, we can interact with them, and trigger a setUrl function on a value.

//add this to your functions.php add_filter('gfexcel_value_object',function($value, $field) {     if($field->formId == 1 && $field->id == 2) {         $value->setUrl('https://wordpress.org');     } }, 10, 2); 

By default the notes are disabled for performance. If you’d like to add these to the row you can activate this like so:

//add this to your functions.php add_filter('gfexcel_field_notes_enabled','__return_true'); //or add_filter('gfexcel_field_notes_enabled_{formid}','__return_true'); // e.g., gfexcel_field_notes_enabled_2 

Definitely! You get to change: text color, background color, bold and italic. If that is not enough, maybe you should add clip art!

//add this to your functions.php add_filter('gfexcel_value_object', function (BaseValue $value, $field, $is_label) {     // Need to know if this field is a label?     if (!$is_label) {         return $value;     }      $value->setColor('#ffffff'); //font color, needs a six character color hexcode. #fff won't cut it here.     $value->setBold(true); // Bold text     $value->setItalic(true); // Italic text (to be combined with bold)     $value->setBackgroundColor('#0085BA'); // background color      // $field is the GF_Field object, so you can use that too for some checks.     return $value; }, 10, 3); 

Yes, this can happen. Unfortunately, this isn’t something that can be fixed without modifying your server configuration.
As a default, WordPress allocates 40 MB of memory. Because the plugin starts the rendering pretty early, it has most of it available.
But every cell to be rendered (even if it’s empty) takes up about 1KB of memory. This means that you have (roughly)
40 MB * 1024 KB = 40,960 Cells. I say roughly, because we also use some memory for calculations and retrieving the data.
If you’re around this cell-count, and the renderer fails; try to upgrade the WP_MEMORY_LIMIT. Checkout WooCommerce’s Docs for some tips.

You can hide a row by adding a hook. Checkout this example:

add_filter('gfexcel_renderer_hide_row', function ($hide, $row) {      foreach ($row as $column) {          if ($column->getFieldId() === 1 && empty($column->getValue())) {              return true; // hide rows with an empty field 1          }      }      return $hide; // don't forget me!  }, 10, 2);
