Extract text from Lightroom catalogs (MCAT)
To convert MCAT catalogs to another format, you need Adobe Lightroom or other Database software.
To convert other file formats to the "Lightroom CC Catalog" file type, you need software like Adobe Lightroom or a similar tool.
An .MCAT file is a specialized local catalog database utilized by Adobe Lightroom CC to manage photo libraries. Usually named Managed Catalog.mcat, this file acts as the central brain of the cloud-centric Lightroom application. It stores crucial information including photo metadata, file locations, star ratings, and step-by-step editing instructions (such as exposure tweaks and AI masks).
This format is managed exclusively by Adobe Lightroom. Users typically encounter the need to convert or extract data from an .MCAT file when they cancel their Adobe subscription, attempt to migrate to competing software, or need to recover lost edits from a corrupted local catalog. The primary disadvantage of the current format is that it is a proprietary, closed-ecosystem file. It does not contain any actual image pixels, meaning you cannot open it in standard web browsers or generic image viewers. Your editing work is entirely locked inside Adobe's database structure.
If you are looking to extract your actual photos, the best conversion target is to export them directly from Lightroom as JPG or DNG files. If you only want to extract the underlying database records, standard relational database formats like CSV, SQL, or plain TXT are the best targets. However, translating the proprietary slider values into another photo editor's format is generally impossible without official migration tools.
Standard online converters fail to process .MCAT files because they mistakenly treat them as raster images rather than complex relational databases. Because the .MCAT format is built on an underlying SQLite framework, our analysis can detect the embedded database tables, making raw text viewing or basic data conversion an achievable reality.
Convert.Guru analyzes your MCAT file, detects the exact format, and lets you read the text inside.
If you want to convert MCAT file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Adobe Lightroom or similar software from the "Photo Metadata Database" 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 MCAT, try Adobe Lightroom or another comparable tool in the "Photo Metadata Database" 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 MCAT converter.
