Convert STC files online for free
The converter easily converts your STC file to various formats - free and online. No Blender or extra software needed.
The converter also works in reverse, so you can convert other Spreadsheet formats to STC with high quality output.
The .stc extension primarily identifies the legacy OpenOffice/StarOffice 1.0 Spreadsheet Template. These files are the ancestors of modern OpenDocument standards (ODF), used to store formatting, formulas, and macros for creating new spreadsheets. While they were the standard in the early 2000s, modern suites like Microsoft Excel often struggle to open them directly, frequently triggering "file format not valid" errors or stripping away complex formatting during import. Additionally, this extension is heavily used in industrial settings as a Label Design Template for cablabel S3 or SATO printers. These proprietary label files contain barcode definitions and layout logic that standard document viewers cannot interpret.
For spreadsheet users, the lack of native support in cloud apps like Google Sheets makes conversion essential. To edit the data in modern environments, users should convert .stc to XLSX or ODS. For archiving or sharing fixed layouts, converting to PDF is recommended to preserve the original visual structure. If you are dealing with a label file, converting to a raster format like PNG or JPG allows for quick previews without needing expensive industrial printing software.

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 STC converter.
