PivotDataExport

Dynamic group, aggregate, sort, pivot data. Output to json, xml, csv or via DataTable. Csv or json with or without header row.

Built on an idea: receive field definitions via api. Fetch, process and return data as result from api, alternatively queue it up and save a file somewhere, that later can be downloaded. So the idea is a dynamic report/export engine that can power a single api (per topic/data source). Kind of similar to GraphQL, but only for reporting/exports. Maybe an api that implement this concept, could be called PivotQL. This library is not PivotQL thou, it is an engine that could power such api.

Example:

Test data used: https://excelbianalytics.com/wp/wp-content/uploads/2020/09/5m-Sales-Records.zip

Read data:

List<CsvRow> salesRecords = null!;
using (var reader = new StreamReader(@"d:\5m Sales Records.csv"))
using (var csv = new CsvReader(reader, CultureInfo.InvariantCulture))
{
  var records = csv.GetRecords<CsvRow>();
  salesRecords = records.ToList();
}

Create fields:

var fields = new List<Field>();

fields.Add(new Field<CsvRow, string>(nameof(CsvRow.Region), rows => Aggregators.CommaList(rows, row => row.Region))
{
  GroupIndex = 0,
  Area = Area.Row,
  SortOrder = SortOrder.Asc
});
fields.Add(new Field<CsvRow, string>(nameof(CsvRow.Country), rows => Aggregators.CommaList(rows, row => row.Country))
{
  GroupIndex = 1,
  Area = Area.Row,
  SortOrder = SortOrder.Desc
});

fields.Add(new Field<CsvRow, string>(nameof(CsvRow.ItemType), rows => Aggregators.CommaList(rows, row => row.ItemType))
{
  GroupIndex = 0,
  Area = Area.Column,
  SortOrder = SortOrder.Desc
});
fields.Add(new Field<CsvRow, string>(nameof(CsvRow.SalesChannel), rows => Aggregators.CommaList(rows, row => row.SalesChannel))
{
  GroupIndex = 1,
  Area = Area.Column,
  SortOrder = SortOrder.Asc
});

fields.Add(new Field<CsvRow, long>(nameof(CsvRow.UnitsSold), rows => rows.Sum(r => r.UnitsSold)));

Group, aggregate, sort:

var pivot = new Pivoter<CsvRow>(salesRecords, fields);
var data = pivot.GetGroupedData_FastIntersect();
var pres = new Presentation<CsvRow>(data);

Get table:

var nested_kv_tbl = pres.GetTable_NestedKeyValueList_VariableColumns();

Code:

using (var f = File.Open(@"d:\pivottest\test5mill_nested_kv.json", FileMode.Create))
{
	JsonSerializer.Serialize(f, nested_kv_tbl, new JsonSerializerOptions { WriteIndented = true });
}
