Welcome to Seal Report & Task

Seal Report & Task offers a complete framework for producing daily reports from any database or any No SQL source, and to perform complex tasks.
The product focuses on easy installation and report design: Once setup, reports can be built and published in a minute.

Seal Report is an Open Source tool for the Microsoft .Net Framework entirely written in C#.

Main Features

  • Dynamic SQL sources: Use either your SQL or let the Seal Engine build dynamically the SQL used to query your database.
  • LINQ queries: Join and query any Data Sources (SQL, Excel, XML, Mongo DB, Olap Cube, HTTP JSon, etc.) with the power of LINQ queries.
  • Native Pivot Tables: Simply drag and drop elements directly in a pivot table (Cross Tab) and display them in your report.
  • HTML 5 and ScottPlot Charts: Define and display Chart Series in two mouse clicks (Support of ChartJS, NVD3, Plotly, ScottPlot and Gauges libraries).
  • Fully Responsive and HTML Rendering using Razor engine: Use the power of HTML5 in the report result (Bootstrap layout, Responsiveness, Tables sorting and filtering). Customize your report presentation in HTML with the Razor engine parsing.
  • Excel and PDF: Have a full control of your report result in Excel (use of EPPLus library) or PDF (use of QuestPDF library). Several other formats are available (XML, Json, Text, CSV) or can be easily customized.
  • KPI and Widget Views: Create and display your Key Performance Indicators in a single report.
  • Web Report Server: Publish your reports on the web (Support of Windows and Linux OS with .NET Core).
  • Report scheduler: Schedule your report executions and generate results in folders, FTP, SFTP server or send them by emails (integrated with the Windows Tasks Scheduler or available as a service).
  • Drill Down navigation and Sub Reports: Navigate in your report result to drill to a detail or to execute another report.
  • Report Tasks: Define tasks to perform your ETL or batch operations (data load, excel load, file download from FTP or SFTP, zip, backup, data processing, etc.) or to trigger procedures from external assemblies.
  • Low TCO (total cost of ownership): The product is designed for minimal ongoing maintenance.

Installation and Compilation


Get the last product releases and source codes at Github.


Just run the setup executable file to install Seal Report on your computer.
The setup will install the Report Designer, the Server Manager, the Seal Scheduler Service and the Task Scheduler with a default repository.

All executables, libraries and configuration files are installed by default in C:\Program Files\Seal Report.
All repository files are installed by default in C:\ProgramData\Seal Report Repository.

Web Report Server Distribution:
The sub-folder C:\Program Files\Seal Report\Web and C:\Program Files\Seal Report\NETCore contain the files required to publish the Web Report Server.

To publish the Web Report Server on IIS, run the Server Manager and select the menu Configuration->Publish Web Site on IIS... to execute the Web Server Publisher wizard.

To publish the Web Report Server on Linux or Azure, Check dedicated deployment tutorials.


Using Visual Studio, open the solution file Seal.sln located at the root directory.
The solution contains the following projects:

  • SealLibrary: Main library shared by all the executables. This library contains the main classes in the Model sub-folder (like Report, MetaTable, Restriction, Task, etc.) plus some helpers.
  • SealLibraryWin: Same library as SealLibrary but compiled for the Windows applications: Report Designer and Server Manager.
  • SealReportDesigner: Report Designer executable (linked with SealLibraryWin).
  • SealServerManager: Server Manager executable (linked with SealLibraryWin).
  • SealTaskScheduler: Console application invoked by the Windows Task Scheduler to execute report in batch.
    This application may also be executed by the Scheduler Service, the Scheduler Worker or the Web Server if the Windows Task Scheduler is not used.
  • SealWebServer: Asp.Net application for Web Report Server.
  • SealSchedulerService: Seal Report Scheduler executable for the Windows Service.
  • SealSchedulerWorker: Seal Report Scheduler executable as a Worker process (for non-Windows OS).
  • Tests: Contains unitary tests and basic samples.
  • TestNuget: Test of the current SealReportLibrary.NETCore Nuget package.
  • SealDocumentation: sealreport.org Web site.

Deployment and publication

Main Entities: Repository and Reports

The Seal Repository stores all the entities managed by Seal Report: Data Sources, Devices, Reports.
In addition, the repository contains extra folders for the Settings (configuration and dictionary for translations), the Views (used to render report result), the Security (configuration and providers).
By default, the repository root folder is located in "C:\ProgramData\Seal Report Repository".

A report is composed of Data Sources, Models, Views and optional Tasks, Outputs and Schedules. The report may also reference Views Templates located in the repository.

  • Data Sources contain the descriptions of database connections, tables, joins and columns.
  • Models define how to generate the ResultSet (Data Table) and Series from a single SQL Statement.
  • The Views are used to generate a HTML document from the Models using Razor parsing and rendering.
  • Output and Schedule can be defined to automate report generation (e.g. Sending an Email every morning).
  • Tasks may be defined to perform SQL or Script tasks.

Product Components

Seal Report is made of the following componts:

  • The Server Manager (a Windows application) edits repository Data Sources, Devices and is used to perform administrative tasks (checking sources and reports, publishing web site, configuring the server, editing the security, etc.).
  • The Report Designer (a Windows application) to create, edit and execute reports.
  • The Web Report Server (an ASP.Net application) allows the end-users to edit and execute the reports published from the Web.
  • The Task Scheduler (a console application) is invoked by the Windows Task Scheduler to schedule report execution on a Device (folder or email).
  • The Scheduler Service (a Windows Service application) to execute the report schedules defined in the repository (folder, file server or email).
  • The Scheduler Worker (a .NET Worker Application) to execute the report schedules defined in the repository (folder, file server or email) on a non-Windows OS.

Repository Folders

Several sub-folders are located from the Repository Root folder. These folders contain all files necessary to run Seal Report.

  • Assemblies: additional DLL (*.dll) that can be referenced in all Razor scripts. You can add your own assemblies in this folder and call them from any script compiled and executed during a report execution (e.g. in a Task).
  • Databases: dedicated folder for local database files (e.g. an MS Access file, an Excel file).
  • Devices: the device configurations (*.scfx) used by the report output. 3 types of devices are available: Folder, File Server (FTP, SFTP), Email to send it to a user by SMTP.
  • Logs: the daily log files (*.txt). All events, executions and schedules messages are logged in a daily file (files are auto-purged).
  • Reports: the reports (*.srex), files and sub-folders published by the Web Report Server. The Reports root folder is the parent of all folders, files and reports published.
  • Security: the security defined for the Web Report Server (Security.xml) and a sub-folder containing the security providers (*.cshtml) available.
  • Settings: the Server configuration (Configuration.xml) and the translation files (*.csv).
  • Sources: the data source files (*.scfx) available for the reports. These data sources are shared amongst all the reports.
  • Sources\TableTemplates: table templates (*.cshtml) referenced by No SQL tables defined in LINQ Data Sources.
  • Sources\TaskTemplates: tasks templates (*.cshtml) referenced by Report Tasks defined in reports.
  • SpecialFolders\Personal: dedicated folder to store personal folders for each user. The folder contains reports, files and the user's profile (_profile.xml).
  • SpecialFolders\Schedules: report schedules (*.xml) when the Seal Report Scheduler is used. One file per schedule.
  • SubReports: the sub-reports (*.srex) referenced by an element in a data source. Sub-Reports allow master-detail navigation from a report result.
  • Views: the view templates (*.cshtml) used by the report views with their configuration and their related JavaScript, CSS and image files.
  • Views\Renderers: the renderer templates (*.cshtml) used by the report views with their configuration to generate report results in a specific format.
