テキストファイルをインポートしてデータ処理を高速化

5月 7, 2025
プレーンテキスト(txt)ファイルを.NET WinFormsアプリのスプレッドシートにすばやく読み込むことで、手動入力を減らし、データの処理と分析を高速化

Importing TXT files into spreadsheet applications allows developers and users to load in plain text data, typically delimited by characters such as commas or tabs, and transform it into structured, editable tables within a spreadsheet-like environment. This process enables users to work with externally sourced or manually created text data using the familiar tools and features of a spreadsheet, such as sorting, filtering, and formula calculations. Loading a text file into an Excel-like format removes the need for manual data entry and simplifies data processing. Support for TXT file imports makes spreadsheet applications more versatile by improving the integration of external data and helping users process information more efficiently. It reduces the workload associated with data processing and ensures that data is quickly available in a usable format for analysis or reporting.

Several WinForms spreadsheet controls allow you to import files in TXT format:

  • DevExpress WinForms Spreadsheet (part of DevExpress WinForms) provides Excel inspired functionality and supports the import of data from TXT files to populate a spreadsheet.
  • Spread.NET WinForms (part of Spread.NET by MESCIUS) enables spreadsheet apps to open delimited text files, instantly converting text content into interactive spreadsheet cells.
  • Aspose.Cells for .NET is a WinForms-compatible programming API for spreadsheet management and processing that includes support for loading TXT files.
  • Telerik WinForms Spreadsheet (part of Telerik UI for WinForms) enables you to import plain text files with tab separated values (.txt) to transform raw data for easy manipulation.

開発者向けに構築された柔軟なコンポーネントを使用して、ソフトウェアでPDFファイルを簡単に作成、編集、表示可能

PDF components provide developers with a set of tools for programmatically handling Portable Document Format (PDF) files within applications. These components enable both the creation and manipulation of PDF documents, supporting a wide range of document workflows across platforms and industries. By integrating such components, developers can build features for generating reports, rendering documents for viewing, or embedding print-ready files in business applications, often without relying on external software or services.

Common features include:

  • Creating PDFs allows developers to generate PDF files dynamically from scratch or from templates, often with full control over layout, fonts, and content.
  • PDF Reader/PDF Viewer functionality enables applications to render and display PDF documents interactively, supporting zoom, navigation, and annotations.
  • Printing/Saving to PDF provides an option to export content or print output directly into a PDF file, preserving formatting and layout.
  • Right to Left (RTL) Support ensures that content in languages such as Arabic and Hebrew is displayed correctly, including text alignment and reading order.
  • Searching Text allows users to locate and highlight specific terms or phrases within a PDF document.
  • Saving a PDF to a Stream enables in-memory saving of PDF documents, which is particularly useful for web services and APIs where disk I/O is limited.
  • Opening Existing PDFs from Stream provides a way to load and manipulate PDF files directly from memory streams, improving performance and enabling secure handling of sensitive documents.

Blazorアプリに豊富なレポートを簡単に追加

5月 6, 2025
柔軟で応答性の高いビューアコンポーネントを使用して、対話型でデータが豊富なレポートをBlazor UIに直接埋め込み可能

A report viewer is a UI element that renders and displays pre-built reports within a Blazor web application, allowing users to interact with them through features like pagination, parameter input, search, and export. It serves as the front-end interface for consuming reports generated by a reporting engine, often backed by data from databases or APIs. For developers, it enables seamless integration of reporting capabilities into Blazor applications without requiring page reloads or external viewers, supports responsive design for various devices, and maintains a consistent user experience through Blazor's component-based architecture.

Several Blazor Reporting Controls offer support for a report viewer including:

  • DevExpress Reports (Multi-Platform) (part of DevExpress Reporting) allows you to embed a native Blazor report viewer, with preview and export functionality.
  • ActiveReports.NET by MESCIUS lets you integrate a Blazor report viewer with customizable UI, supporting client-side export to multiple formats.
  • Stimulsoft Reports.Web facilitates embedding a Blazor viewer that supports interactive reports, multiple display modes, and various export options.

Spread.NET v18.1では、複雑なスプレッドシートデータを対話型の3Dサーフェスに変換する新しいWPFサーフェスチャートを追加

Spread.NET by MESCIUS is a powerful tool for building Excel-like applications in your .NET projects. It lets you create interactive spreadsheets, grids, dashboards, and even forms within WinForms, ASP.NET, and WPF applications. With its rich feature set, including a robust calculation engine, formula support, and Excel compatibility, Spread.NET empowers developers to build data analysis tools, budgeting apps, scientific dashboards, and more, all within the familiar .NET environment.

The Spread.NET v18.1 update introduces a new surface chart feature for WPF, providing developers with the capability to render spreadsheet data on a three-dimensional plane. By offering this advanced charting functionality, developers can create more sophisticated data visualization solutions within their WPF applications, allowing end-users to gain deeper insights into complex data and identify key correlations that may not be evident in two-dimensional representations. This feature expands the analytical tools available within Spread.NET, allowing for more nuanced and comprehensive data exploration.

To see a full list of what's new in v18.1, see our release notes.

Spread.NET is licensed per developer and is available as a Perpetual License with a 12 month support and maintenance subscription. We can supply any Spread.NET license including new licenses, maintenance renewals, and upgrade licenses. See our Spread.NET licensing page for full details.
