What is a FMT file?
A .FMT file is a format layout file used by many different software applications to define how data is structured, printed, or displayed. Because "FMT" simply stands for "format", this extension is highly overloaded. It can represent a label design format for barcode software like BarTender or NiceLabel, a FoxPro Format File created by Microsoft, an Optical Mark Recognition (OMR) form definition, or an SQL bulk copy format file used by Microsoft SQL Server. It may contain plain text, XML, or binary data depending on the originating software.
How to open FMT files?
Because the .FMT extension has multiple possible meanings, you must first identify the correct creator software. If the file is plain text or XML, you can open it with a text editor like Notepad++ or Visual Studio Code. If it is a database or label format, you will need the specific application, such as dBASE or ZebraDesigner.
Best practices and troubleshooting
Do not assume every .FMT file opens with the same program. Inspecting the raw text inside the file often reveals clues about its origin. For example, SQL Server format files often start with version numbers, while label formats may contain XML tags. If you need the data in a different format, you can convert your file on convert.guru to sensible target formats like .TXT, .CSV, or .XML.
Software and tools
Common tools associated with .FMT files include Microsoft SQL Server bcp, Aptech Systems GAUSS, Datasis OMR, and Software DELSOL. Command-line utilities and database administrators frequently use these files for bulk data imports and exports.
Summary
viewer.online/fmt can analyze .FMT files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available. Since .FMT has multiple possible meanings, viewer.online/fmt is useful for identifying, inspecting, and understanding .FMT files without installing software or dealing with compatibility problems.
