What is HeidiSQL?

HeidiSQL is a versatile, free software application designed for managing databases. Initially created in 2002 by an individual named Ansgar, it has since become one of the most popular database management tools, especially for MariaDB and MySQL databases. As a Windows application, HeidiSQL is compatible with a range of Windows operating systems, including Windows 10 and 11, and also runs on Windows 7 and 8 with some minor issues.

This user-friendly tool is renowned for its ease of learning and comprehensive features that cater to various database management needs. HeidiSQL enables users to connect to multiple servers within a single window and offers a variety of connection methods, such as command line, SSH tunnel, and SSL settings. Users can effortlessly create, view, and modify tables, stored routines, triggers, and more. Additionally, HeidiSQL boasts powerful data export capabilities, supporting formats like CSV, HTML, XML, and even PHP Arrays, among others.

HeidiSQL’s functionality extends to managing user privileges, importing and exporting text files, and executing custom queries. It also provides a grid for browsing and editing table data, as well as features for bulk table editing. For advanced users, HeidiSQL can launch a parallel mysql.exe command line window to utilize the current connection settings, further enhancing its utility as a comprehensive database management solution.

Exporting Data to CSV in HeidiSQL

Using the Context Menu for CSV Export

To export data to a CSV file in HeidiSQL, you can simply right-click on any data result. Once you've done that, click on "Export grid data" to initiate the CSV export process. After selecting this option, you will be prompted to set the destination where the CSV file will be saved. The CSV file is generated after you specify the location and confirm the export.

Loading and Exporting Complete Data Sets

By default, HeidiSQL loads 1000 rows in the underlying grid. To export the complete set of data, first ensure all rows are loaded by clicking the "Show all" button located at the top right of the grid. This action loads all rows up to the maximum limit of 100,000 rows that HeidiSQL can handle. Once all the desired rows are visible, follow the same right-click process on the grid and select "Export grid data" to save the full dataset as a CSV file.

Adjusting the Number of Rows for Export

If you need to export a different number of rows than the default or maximum, you can adjust the number of rows loaded in the grid. Go to the "Tools" menu, select "Preferences", and then "Grid formatting". Here, you can change the settings to load the specific number of rows you require for your CSV export. After adjusting these settings, you can proceed with the right-click and "Export grid data" method to export the adjusted set of rows to a CSV file.
