28.1.7. Layer tools
28.1.7.1. Export layer(s) information
Creates a polygon layer with features corresponding to the extent of selected layer(s).
Additional layer details (CRS, provider name, file path, layer name, subset filter, abstract and attribution) are attached as attributes to each feature.

import processing
processing.run("algorithm_id", {parameter_dictionary})
The algorithm id is displayed when you hover over the algorithm in the Processing Toolbox. The parameter dictionary provides the parameter NAMEs and values. See Using processing algorithms from the console for details on how to run processing algorithms from the Python console.
28.1.7.2. Export to spreadsheet
Exports the attributes of a selection of vector layers into a spreadsheet document or optionally appends them to an existing spreadsheet as additional sheets.

[vector: any] [list] |
Input vector layers. The output spreadsheet will consist of a sheet, for each layer, that contains the attributes of this layer. |
Use field aliases as column headings |
|
[boolean] Default: False |
Use the field aliases from the attribute table for the spreadsheet. |
Export formatted values instead of raw values |
|
[boolean] Default: False |

28.1.7.3. Extract layer extent
Generates a vector layer with the minimum bounding box (rectangle with N-S orientation) that covers all the input features.
The output layer contains a single bounding box for the whole input layer.
