# target-csv
A [Singer](https://singer.io) target that writes data to CSV files.
## How to use it
`target-csv` works together with any other [Singer Tap] to move data from sources like [Braintree], [Freshdesk] and [Hubspot] to CSV-formatted files. It is commonly used for loading data into tools like Excel or simply storing a backup of the source data set.
### Install
We will use [`tap-exchangeratesapi`][Exchangeratesapi] to pull currency exchange rate data from a public data set as an example.
First, make sure Python 3 is installed on your system or follow these installation instructions for [Mac] or [Ubuntu].
It is recommended to install each Tap and Target in a separate Python virtual environment to avoid conflicting dependencies between any Taps and Targets.
```bash
# Install tap-exchangeratesapi in its own virtualenv
python3 -m venv ~/.virtualenvs/tap-exchangeratesapi
source ~/.virtualenvs/tap-exchangeratesapi/bin/activate
pip install tap-exchangeratesapi
deactivate
# Install target-csv in its own virtualenv
python3 -m venv ~/.virtualenvs/target-csv
source ~/.virtualenvs/target-csv/bin/activate
pip install target-csv
deactivate
```
### Run
We can now run `tap-exchangeratesapi` and pipe the output to `target-csv`.
```bash
~/.virtualenvs/tap-exchangeratesapi/bin/tap-exchangeratesapi | ~/.virtualenvs/target-csv/bin/target-csv
```
The data will be written to a file called `exchange_rate-{timestamp}.csv` in your working directory.
```bash
› cat exchange_rate-{timestamp}.csv

```
### Optional Configuration
`target-csv` takes an optional configuration file that can be used to set formatting parameters like the delimiter - see [config.sample.json](config.sample.json) for examples. To run `target-csv` with the configuration file, use this command:
```bash
~/.virtualenvs/tap-exchangeratesapi/bin/tap-exchangeratesapi | ~/.virtualenvs/target-csv/bin/target-csv -c my-config.json
```
