### Advanced Templating
### Templating
The OpenRefine [Templating](https://github.com/OpenRefine/OpenRefine/wiki/Export-As-YAML) supports exporting data in any text format (i.e. to construct JSON or XML).

Because our project "advanced" contains duplicates in the first column "email" this command will overwrite files (e.g. `advanced_melanie.white@example2.edu.json`).
When using this option, the first column should contain unique identifiers.
### Append data to an existing project
OpenRefine does not support appending rows to an existing project.
As long as the [feature request](https://github.com/OpenRefine/OpenRefine/issues/715) is not yet implemented, you can use the openrefine-client to script a workaround:
1. export existing project as csv
2. put old and new data into a zip archive
3. create new project by importing the zip archive
Here is an example that replaces the existing project:
```
openrefine-client --export myproject --output old.csv
openrefine-client --delete myproject
zip combined.zip old.csv new.csv
openrefine-client --create combined.zip --format csv --projectName myproject
```
Note that the project id will change.
If you want to distinguish between old and new data, you can use the additional flag includeFileSources:
```
openrefine-client --create combined.zip --format csv --projectName myproject --includeFileSources true
```
