This application features a very versatile import and export feature in order

to offer the best experience possible and allow you to freely choose where your data goes.

!!! warning "WIP"
|

The Module is relatively new. There is a know issue with [Timeouts](https://github.com/vabene1111/recipes/issues/417) on large exports.
|
||||
A fix is being developed and will likely be released with the next version.
|
||||
|
||||
The Module is build with maximum flexibility and expandability in mind and allows to easily add new
|
||||
integrations to allow you to both import and export your recipes into whatever format you desire.

## Default
|
||||
The default integration is the build in (and preferred) way to import and export recipes.
|
||||
It is maintained with new fields added and contains all data to transfer your recipes from one installation to another.

|
||||
Safron exports do not contain any images. They will be lost during import.
|
||||
|
||||
## Paprika
|
||||
Paprika can create two types of export. The first is a proprietary `.paprikarecipes` file in some kind of binarized format.
|
||||
The second one is HTML files containing at least a bit of microdata.
|
||||
A Paprika export contains a folder with a html representation of your recipes and a `.paprikarecipes` file.
|
||||
|
||||
If you want to import your Paprika recipes follow these steps
|
||||
|
||||
1. create a html export
|
||||
2. Create a `.zip` file from the `Recipes` folder (next to the `index.html`) the structure should look like this
|
||||
```
|
||||
Recipes.zip/
|
||||
└── Recipes/
|
||||
├── recipe one.html
|
||||
├── recipe two.thml
|
||||
└── Images/

|
||||
```
|
||||
3. Upload the zip file in the import module and import it
|
||||
The `.paprikarecipes` file is basically just a zip with gzipped contents. Simply upload the whole file and import
|
||||
all your recipes.
