Compare CSViewer vs. ConvertCSV

CSViewer is a quick and free desktop application for Windows that allows users to view and analyze extensive delimited text and binary files, including formats like CSV, TSV, Parquet, and QVD. The application can effortlessly load millions of rows in just a few seconds and provides sophisticated filtering options alongside immediate profiling features, including aggregate functions, null counts, and outlier identification. Users can easily export their filtered datasets, save their analysis configurations, and create visualizations through charts and cross-tabulations. With a focus on facilitating exploratory data analysis without relying on cloud services, CSViewer ensures that all aggregates and visual elements refresh instantaneously whenever a filter is applied or modified. Each column's statistics, including null counts, unique values, and minimum or maximum values, are readily available for review. Additionally, users have the option to export their selected rows into a new file for sharing purposes or further analysis in other applications. The software also supports converting files between different formats, such as transforming CSV files into QVD format. When users choose to export to the native .dset format, their data is preserved alongside any applied filters and visualizations, ensuring that their work can be conveniently revisited later. This comprehensive approach streamlines data handling and enhances the user experience.

ConvertCSV is a web-based application that facilitates the conversion of CSV files to various formats, including JSON, XML, SQL, KML, YAML, and Markdown, among others. It features a range of utilities, such as CSV viewers and editors, as well as tools designed for data extraction, including emails and URLs. Users can execute operations like querying CSV files using SQL, splitting large datasets, and converting CSV files into fixed-width formats, Excel sheets, or PDFs. The entire processing is done on the client-side, ensuring user privacy, and it is capable of handling large files efficiently. With the ability to use SQL for querying and writing data back to CSV or JSON, users have powerful options at their disposal. The tool's default setting includes an auto-detect mode for field separators, making it user-friendly. Additionally, users can extract emails or URLs from websites, filter data to include or exclude specific records, and sort data either alphabetically or numerically. There is also an option for including double or single quotes around values, while the application can treat all quotes as data when needed. Importantly, all operations occur completely on the client-side, meaning that your data remains securely on your device. This ensures a high level of confidentiality and control over your information throughout the conversion process.
