Bulk file convertor QGIS plugin/program

Question

EDIT - please link any similar questions as this needs testing on QGIS 3

Similar questions have been asked but without I think non "script" solutions

Is there a easier to use for non technical users for QGIS plugin/program to bulk export files? Say shp files to .kml files?

I believe a program: Expert GPS Pro that would do this, but this $299.95 at the time of writing. (http://www.expertgps.com/)

EDIT

Cannot get plugin to work based on answer

Get error: 'NoneType' object has no attribute 'CreateDataSource' See log for more details

Tried kml to shp and shp to kml Autofill settings, used Do not autofill for each test. Perhaps this plugin is better in newer QGIS versions

In QGIS 2.2:

Output layer doesn't remember where you saving the files too
You have to fill the output layer in multiple times. The path (location to save files isn't remembered)
This bulk convert probably takes longer to setup than manually saving each file for a small number

How could you replicate Save Vector Layer Export settings, such as DataSource Options, Layer Options, Custom Options ect... via Creation Options Settings, so that the conversion is the "same"?

If you export kml files, I think you sometimes need to remove the altitude component via: Datasource Options, AltitudeMode: ClampToGround, so is this or other "settings" still possible via Creation Options?

I ask as I would assume you would still need to manually export files, if the settings are not "transferable" to the Convert Format.

www.geofileconverter.com this website above helps easily convert geographic file formats for example shp, csv, wkt, gml, kml... it is based on the OGR libraries. — Elasri Abdessadek, Oct 15 '18 at 22:41
@ElasriAbdessadek Thanks, just wanted this inside QGIS, but this question is out of date. I've just got back access to stackexchange — maskin, Oct 17 '21 at 15:26

Yes, there is. its called "Convert format". Go to processing toolbox and run it from there by right click then run as batch processing.

UPDATE :

put as follow in creation option column:

-dsco AltitudeMode=absolute -dsco NameField=Name -dsco DescriptionField=Description

For example, in my case will be

-dsco AltitudeMode=clampToGround -dsco NameField=NAME_1 -dsco DescriptionField=Description

TEST RESULT

Be Careful, when insert the creation option attribute (No space at the end allowed, seems it affecting the result):

Wrong → Right →

This extra description value can be modified as you need like AltitudeMode can be clampToGround or relativeToGround like the one that you see within "Save as" method.

UPDATE 2 - Alternative

-dsco altitudeModeEnum=clampToGround -dsco NameField=Name -dsco DescriptionField=description

Alternative option has been tested.

Thanks! :-) Could you explain the creation options? I would like to keep Datasource options, altitudeMode - clamptoGround Will add more information to question. – maskin Jul 05 '16 at 10:21

you can see updated answer. May it help?? – Maruli Uje Indo Jul 05 '16 at 13:33
Thanks, that helps. Do you know if this gives the same result, has this been tested at all? – maskin Jul 06 '16 at 12:35
I am not sure how you might confirm these settings work, but I hope this comment doesn't come across rude, I am not sure how you would tell? Other than a kml has exported. – maskin Jul 06 '16 at 12:36
it's ok.. yes, it was updated and tested. – Maruli Uje Indo Jul 06 '16 at 12:57
Is it works for you? – Maruli Uje Indo Jul 06 '16 at 16:56
thanks, I haven't had time to test it yet, thanks for your help. – maskin Jul 12 '16 at 07:36
Done a few tests, keep getting an error when using QGIS 2.2 Perhaps if other versions are used this plugin works. – maskin May 25 '17 at 14:58

The answer provided by @UjeIndo seems to be the correct one although I am also unsure how to exactly use the Creation Options. But if you have loaded your shapefiles into QGIS, you could loop through each one and save it as a .kml file specifying the datasourceOptions by using the following in the Python Console:

result_path = "path/to/directory/"
for layer in QgsMapLayerRegistry.instance().mapLayers().values():
    QgsVectorFileWriter.writeAsVectorFormat(layer, result_path + layer.name(), "utf-8", None, "KML", datasourceOptions='your_text')

Thank you :-) but I am looking for non "script" options as this is more practical to explain to other users of QGIS I know.
Unless you know of a dummies/step by step guide to running this in Python Console that I could share? :-) but I don't wish to ask too much of your time.

@maskin - Most welcome, there are other plugins available which convert shapefiles to kml such as Batch Save Layers and Bulk vector export but I don't think either of these support adding in custom options. But to run the above code, you can copy/paste it to a text editor, change the result_path and datasourceOptions, press Ctrl + Alt + P in QGIS to load up the python console, then paste the code and hit Enter twice ;) – Joseph Jul 05 '16 at 12:21
Thanks, I would like to expand your answer with your comment if that is possible? To highlight that the plugins are experimental so users can better find them. – maskin Jul 05 '16 at 12:39

i have updated my answer by adding description attribute to creation option. is it that you are looking for? – Maruli Uje Indo Jul 05 '16 at 13:38
@maskin - Apologies, I keep forgetting that I have it enabled! – Joseph Jul 05 '16 at 14:41

@Joseph No worries. :-) I tend to write longer answers adding in extra detail... – maskin Jul 06 '16 at 12:40

I think the best option might be the installation of the HCMGIS plugin, which has a built-in batch converter.

The plugin appears in the main top bar after installation. You can select:

HCMGIS -> Batch Converter -> Vector format converter

and next select the file extensions to convert: Shp, GeoJSON, CSV, Kml, Gpkg and Gml

This is great but it can only read KML, not write it. So annoying – boulder_ruby Oct 07 '22 at 17:20
Yeah, the plugin like others is at some point restricted. Thanks for raising your issue, I will try to find something other then. – Geographos Oct 11 '22 at 15:02
