### Write CSV Data to IO

Source: https://github.com/jimm/csvlixir/blob/main/README.md

Use `CSVLixir.write` to generate CSV strings and `IO.write` to output them. This example demonstrates writing multiple rows, including one with escaped quotes, to standard output.

```elixir
CSVLixir.write([["abc", "def", "gh",""i"], [123, 456, 789]])
|> Enum.each(&IO.write/1)
#=> abc,def,"gh"",""i"
#=> 123,456,789
#=> :ok
```

### Write CSV Rows to a File Line by Line

Source: https://github.com/jimm/csvlixir/blob/main/README.md

Open a file in write mode (optionally with `:utf8` encoding), and use `IO.write` with `CSVLixir.write_row` to write individual rows to the file.

```elixir
f = File.open!("/tmp/csvlixir.csv", [:write, :utf8])
IO.write(f, CSVLixir.write_row(["garçon", "waiter"]))
IO.write(f, CSVLixir.write_row(["résumé", "resume"]))
File.close(f)

File.read!("/tmp/csvlixir.csv")
# => "garçon,waiter\nrésumé,resume\n"
```

--------------------------------

### Write CSV Data to a File Using Streams

Source: https://github.com/jimm/csvlixir/blob/main/README.md

Open a file in write mode, pipe a stream of CSV data generated by `CSVLixir.write` into `IO.write` for each file chunk, and ensure the stream is fully processed with `Stream.run`.

```elixir
f = File.open!("/tmp/csvlixir.csv", [:write])
1..3
|> Stream.map(&([&1, &1+1 ,&1+2]))
|> CSVLixir.write
|> Stream.each(&(IO.write(f, &1)))
|> Stream.run
File.close(f)

File.read!("/tmp/csvlixir.csv")
# => "1,2,3\n2,3,4\n3,4,5\n"
```

--------------------------------

### Add CSVLixir to Mix Dependencies

Source: https://github.com/jimm/csvlixir/blob/main/README.md

Add CSVLixir to your project's dependencies in `mix.exs`.

```elixir
def deps do
  [{:csvlixir, "~> 2.0.3"}]
end
```

--------------------------------

### Write CSV Data to a Stream

Source: https://github.com/jimm/csvlixir/blob/main/README.md

Use `CSVLixir.write` to transform a list of lists into a stream of CSV strings. Each string in the stream ends with a newline character. Convert the stream to a list to see all output strings.

```elixir
CSVLixir.write([["first", "row"], [123, 456]]) |> Enum.to_list
#=> ["first,row\n", "123,456\n"]
```

--------------------------------

### Read CSV Data from a File

Source: https://github.com/jimm/csvlixir/blob/main/README.md

Use `CSVLixir.read` to read CSV data from a file path. It returns a Stream that generates rows of CSV data. Convert the stream to a list for immediate processing.

```elixir
CSVLixir.read("path/to/my.csv") |> Enum.to_list
#=> [["row", "one"], ["row", "two"]]
```

--------------------------------

### Write a Single CSV Row to a String

Source: https://github.com/jimm/csvlixir/blob/main/README.md

Use `CSVLixir.write_row` to convert a single list into a CSV formatted string, ending with a newline.

```elixir
CSVLixir.write_row(["a", "b", "c"])
#=> "a,b,c\n"
```

--------------------------------

### Parse CSV Data from a String

Source: https://github.com/jimm/csvlixir/blob/main/README.md

Use `CSVLixir.parse` to parse CSV data directly from a string. This function returns a list of lists representing the CSV rows.

```elixir
CSVLixir.parse("abc,def,ghi\n123,456,789")
#=> [["abc","def","ghi"],["123","456","789"]]

CSVLixir.parse(~s{abc,def,"gh"",""i})
#=> [["abc", "def", "gh",""i]]

CSVLixir.parse(File.read!("/tmp/foo.csv"))
#=> [["row", "one"], ["row", "two"]]
```
