# olca-simapro-csv

`olca-simapro-csv` is an API for reading and writing the [SimaPro CSV format](./format.md).

## Usage

Include this dependency in your project:

```xml

  org.openlca

  olca-simapro-csv

  3.0.5

```

You can directly read a CSV data set from a file:

```java

var dataSet = SimaProCsv.read(file);

```

Alternatively, you can read the content of a file block by block. This is useful

when you have large files that do not fit into memory:

```java

SimaProCsv.read(file, block -> {

  if (block.isProcessBlock()) {

    var process = block.asProcessBlock();

    // ...

  } else if (block.isUnitBlock()) {

    var unitBlock = block.asUnitBlock();

    // ...

  }

});

```

A data set can be written to a file:

```java

dataset.write(file);

```

There is also a more low-level API to write data sets to a `CsvBuffer`:

```

CsvDataSet ds = ...

try (var writer = new FileWriter(file, SimaProCsv.defaultCharset())) {

  ds.write(new CsvBuffer(writer, ds.header()));

}

```
