Convert SLK files online for free
The converter easily converts your SLK file to various formats - free and online. No Excel or extra software needed.
The converter also works in reverse, so you can convert other Spreadsheet formats to SLK with high quality output.
The .SLK extension primarily designates the SYLK (Symbolic Link) format, a legacy text-based data interchange standard introduced by Microsoft for Multiplan and Excel. Unlike modern XLSX files which use XML and compression, SYLK files store spreadsheet data in plain ASCII text. While this ensures broad compatibility across disparate systems and databases, it is a key problem for modern workflows: the files are uncompressed and large, lack support for advanced formatting (charts, macros, pivot tables), and frequently trigger security block warnings in newer versions of Excel due to historical vulnerability exploits.
For most users, keeping data in .SLK is impractical. For active editing and data analysis, you should convert these files to XLSX to unlock the full feature set of modern spreadsheets. If you need to import the raw data into a web application or database, converting to CSV is the industry standard.
A secondary, distinct use of the .SLK extension is for audio files encoded with the SILK codec, developed by Skype for internet calling. These files are highly specialized and often refuse to play in standard media players like VLC. To make these recordings accessible or shareable, conversion to MP3 or WAV is essential.
Whether you are dealing with legacy spreadsheet data or proprietary voice recordings, convert.guru allows you to view and convert your .SLK files instantly without navigating complex software settings.
Use Convert.Guru to open and convert your SLK file.

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 SLK converter.
