ConvertCSV vs. CSViewer

ConvertCSV is an online tool that allows users to transform CSV files into a variety of formats such as JSON, XML, SQL, KML, YAML, and Markdown, providing a versatile solution for data management. In addition to these conversions, it offers utilities like CSV viewers and editors, along with data extraction tools that enable users to retrieve emails and URLs effectively. Users can perform various operations, including SQL queries on CSV files, splitting extensive datasets, and converting CSVs into fixed-width formats, Excel documents, or PDFs. The application processes everything on the client-side, which not only protects user privacy but also ensures efficient handling of large files. With SQL capabilities for querying and saving data back to CSV or JSON, users are equipped with robust functionalities. The default setting features an auto-detect mode for field separators that enhances usability. Furthermore, users can extract emails or URLs from different websites, filter data to include or exclude particular records, and sort the information either in alphabetical or numerical order. There’s also the flexibility to add double or single quotes around values, with the option to treat all quotes as data when necessary. Crucially, since all operations are executed entirely on the client-side, users maintain full control over their data, ensuring a high degree of confidentiality throughout the conversion process. This commitment to user privacy and data security underscores the application's reliability and effectiveness in managing and converting data seamlessly.

CSViewer is a fast and free desktop application designed for Windows users, enabling them to view and analyze large delimited text and binary files, including popular formats like CSV, TSV, Parquet, and QVD. It can quickly load millions of rows within seconds and offers advanced filtering capabilities as well as immediate profiling features, which cover aggregate functions, null counts, and outlier detection. Users can effortlessly export their filtered datasets, save their analysis setups, and generate visual representations through charts and cross-tabulations. Prioritizing exploratory data analysis without dependence on cloud services, CSViewer ensures that all aggregates and visual elements are updated in real-time whenever filters are adjusted or changed. Statistics for each column, such as null counts, unique values, and minimum or maximum values, are readily available for users to examine. Furthermore, users can export their selected rows into a new file for sharing or further analysis in different applications. The software also accommodates file conversion between various formats, allowing users to change CSV files into QVD format seamlessly. When opting to export to the native .dset format, users' data, along with any filters and visualizations applied, is preserved, making it easy to revisit their work later. This methodical approach not only simplifies data management but also significantly enhances the overall user experience while providing a robust tool for data analysis. Users can take full advantage of CSViewer’s capabilities to streamline their workflow efficiently.
