SQL Server Management Studio 2012 - Export all tables of database as csv

I have a database in SQL Server with a lot of tables and wish to export all tables in csv format. From a very similar question asked previously - Export from SQL Server 2012 to .CSV through Management Studio

Right click on your database in management studio and choose Tasks ->
Export Data...

Follow a wizard, and in destination part choose 'Flat File
Destination'. Type your file name and choose your options.

What I want is the capability to export all tables at once. The SQL Server Import and Export Wizard only permits one table at a time. This is pretty cumbersome, if you have a very big database. I think a simpler solution might involve writing a query, but not sure.

The export wizard allows only one at a time. I used the powershell script to export all my tables into csv. Please try this if it helps you.

$database = "DATABASE_NAME"
$tablequery = "SELECT name from sys.tables"

#Delcare Connection Variables
$connectionTemplate = "Data Source={0};Integrated Security=SSPI;Initial Catalog={1};"
$connectionString = [string]::Format($connectionTemplate, $server, $database)
$connection = New-Object System.Data.SqlClient.SqlConnection
$connection.ConnectionString = $connectionString

$command = New-Object System.Data.SqlClient.SqlCommand
$command.CommandText = $tablequery
$command.Connection = $connection

#Load up the Tables in a dataset
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $command
$DataSet = New-Object System.Data.DataSet

# Loop through all tables and export a CSV of the Table Data
foreach ($Row in $DataSet.Tables[0].Rows)
    $queryData = "SELECT * FROM [$($Row[0])]"

    #Specify the output location of your dump file
    $extractFile = "C:\mssql\export\$($Row[0]).csv"

    $command.CommandText = $queryData
    $command.Connection = $connection

    $SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
    $SqlAdapter.SelectCommand = $command
    $DataSet = New-Object System.Data.DataSet

    $DataSet.Tables[0]  | Export-Csv $extractFile -NoTypeInformation
