Extract text from MySQL data files (MYD)
To convert MYD data files to another format, you need MySQL or other Database software.
To convert other file formats to the "Relational Database Table File" file type, you need software like MySQL or a similar tool.
A .MYD file contains the actual row data of a MyISAM table used by MySQL and MariaDB relational database management systems. For every MyISAM table created in the database, the system generates three distinct files: a FRM file (table format and schema), a MYI file (indexes), and the .MYD file (the raw data itself).
The .MYD format is a proprietary, closed binary format specific to the MySQL storage engine architecture. It is not a standalone file. You cannot simply open a .MYD file with a text editor or a generic spreadsheet application. The file contains raw binary data that is strictly structured according to the schema defined in the missing FRM file. Relying on MyISAM is increasingly rare as modern systems favor the transactional InnoDB engine, making legacy .MYD files difficult to access or migrate without a running, compatible database server.
Users typically need to convert .MYD files to standard flat formats like CSV, JSON, or SQL dumps to migrate data or analyze it in other tools. However, standard online converters fail to parse the binary rows correctly because they lack the database context and the accompanying schema definition.
This file format is exceptionally difficult to open or convert directly. Only a MySQL server can accurately reconstruct the table. However, you can drag and drop your file onto convert.guru to identify the format, inspect the internal raw strings, and attempt conversion or data extraction if a supported underlying text structure is detected.
Convert.Guru analyzes your MYD file, detects the exact format, and lets you read the text inside.
Users also converted MYI, FRM, MDY, IBDATA1, OPT, RAR, IBD, TXT, MWB, ZIP, EX5, MP4 and PKG files.
If you want to convert MYD file to DB, SQLITE, SQLITE3, MDB, ACCDB, DBF, ODB, FDB, GDB, FRM, SQL or BAK, you can use MySQL or similar software from the "Database Table Storage" category. In the File menu, look for Save As… or Export….
To convert NDF, SQLITE3, BAK, RDB, SQL, DB4, MDF, MDB, LDF, DB, DB3 or SQLITE files to MYD, try MySQL or another comparable tool in the "Database Table Storage" category.
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 MYD converter.
