Convert MYI to another file type
To convert MYI index files to another format, you need MySQL or other Database software.
Convert a file to MYI
To convert other file formats to the "MySQL Storage Engine Index" file type, you need software like MySQL or a similar tool.
About MYI files
A .MYI file stores the index data for a table managed by the MyISAM storage engine in MySQL. These files are typically administered using database management tools like phpMyAdmin or MySQL Workbench. The .MYI format is highly proprietary and useless on its own. You cannot open it in a standard text editor or web browser. It only contains binary pointers designed to speed up database queries, not the actual human-readable data. Furthermore, these files are notoriously fragile; if the server crashes, the index easily corrupts, locking you out of your data. You cannot convert an isolated .MYI file. Instead, you must load the complete table alongside its matching MYD data file and FRM structure file into a database server, and then export it to SQL, CSV, or JSON. Because it is a closed, binary database format, standard online converters fail completely. They expect simple document or image data, not raw database index structures. Often, only the original database software can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your MYI file, detects the exact format, and lets you read the text inside.
If you want to convert MYI file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use MySQL or similar software from the "Database Index Storage" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to MYI, try MySQL or another comparable tool in the "Database Index Storage" category.
The MYI Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our MYI converter.
