Export SQLite to Excel

This line is used to save the exported file in default location.

SqliteToExcel sqliteToExcel = new SqliteToExcel(this, "helloworld.db");

This line is used to save the exported file in used preferred location.

SqliteToExcel sqliteToExcel = new SqliteToExcel(this, "helloworld.db", directory_path);

This code snippet is used to Export a single table in a database to Excel Sheet

sqliteToExcel.exportSingleTable("table1", "table1.xls", new SQLiteToExcel.ExportListener() {
     @Override
     public void onStart() {

     }
     @Override
     public void onCompleted(String filePath) {
     
     }
     @Override
     public void onError(Exception e) {

     }
});

This following code snippet is used to Export a list of table in a database to Excel Sheet

sqliteToExcel.exportSpecificTables(tablesList, "table1.xls", new SQLiteToExcel.ExportListener() {
     @Override
     public void onStart() {

     }
     @Override
     public void onCompleted(String filePath) {
     
     }
     @Override
     public void onError(Exception e) {

     }
});

This code snippet is used to Export a every table in a database to Excel Sheet

sqliteToExcel.exportAllTables("table1.xls", new SQLiteToExcel.ExportListener() {
     @Override
     public void onStart() {

     }
     @Override
     public void onCompleted(String filePath) {
     
     }
     @Override
     public void onError(Exception e) {

     }
});

This code snippet shows how to exclude columns from the export (the resulting export file may not be able to be imported)

ArrayList<String> columnsToExclude = new ArrayList<String>();
columnsToExclude.add("income_id");
sqliteToExcel.setExcludeColumns(columnsToExclude);
...
sqliteToExcel.export...

This code snippet shows how to `pretty` names (either sheet names or column names (the resulting export file may not be able to be imported)

HashMap<String, String> prettyNameMapping = new HashMap<String, String>();
prettyNameMapping.put("income_date", "Date");
sqliteToExcel.setPrettyNameMapping(prettyNameMapping);
...
sqliteToExcel.export...

This code snippet shows how to format the value for a column on export (if you want to convert ID's or whatnot to be better displayed)

sqliteToExcel.setCustomFormatter(new SQLiteToExcel.ExportCustomFormatter() {
    @Override
    public String process(String columnName, String value) {
        switch(columnName) {
            case "income_type_id":
                int v = Integer.parseInt(value);
                switch(v) {
                    case 10:
                        value = "Sale";
                        break;
                    ...
                    default:
                        value = "Unknown";
                        break;
                }
                break;
        }
        return value;
    }
});

Import Excel into Database

The following snippet is used to initialize the library for Importing Excel

ExcelToSQLite excelToSQLite = new ExcelToSQLite(getApplicationContext(), "helloworld.db");

or To drop table while importing the Excel, use the following

ExcelToSQLite excelToSQLite = new ExcelToSQLite(getApplicationContext(), "helloworld.db", true);

The following code is used to Import Excel from Assets

excelToSQLite.importFromAsset("assetFileName.xls", new ExcelToSQLite.ImportListener() {
	@Override
	public void onStart() {

	}

	@Override
	public void onCompleted(String dbName) {

	}

	@Override
	public void onError(Exception e) {

	}
});

The following code is used to Import Excel from user directory

excelToSQLite.importFromFile(directory_path, new ExcelToSQLite.ImportListener() {
	@Override
	public void onStart() {

	}

	@Override
	public void onCompleted(String dbName) {

	}

	@Override
	public void onError(Exception e) {
