Free web BI tool for ad-hoc reporting with online pivot tables and pivot charts by CSV/TSV files or databases (SQL Server, MySql, PostgreSql, Oracle, MongoDb, ElasticSearch). SeekTable allows you to perform ad-hoc analysis of business data with pivot tables and charts. It is very easy to use, with a click you can upload your data (CSV/TSV/Excel file) and build summary reports by selecting dimensions and measures. It is possible to change rows or columns order by clicking on the appropriate labels; also you can exclude rows or columns with help of simple but powerful keyword-based filter. You can save your report, export to PDF, Excel, CSV, Excel worksheet (or even Excel PivotTable), or simply share it to someone by email or with a public link. Reports may be delivered on schedule with help of Zapier or MS Flow. SeekTable can be used for real-time reporting by large datasets when connected directly to SQL database, MongoDb or ElasticSearch. There is no ETL process (data is not imported): SeekTable generates and executes database queries on-the-fly, and you always get up-to-date numbers. For efficient reporting by databases, SeekTable supports user-defined parameters that could be used for database-level data filtering (say, in SQL WHERE).
