Extract text from Origin workbook templates (OTWU)
To convert OTWU workbook templates to another format, you need Origin or other Spreadsheet software.
To convert other file formats to the "Origin Workbook Template" file type, you need software like Origin or a similar tool.
The .otwu file format represents an Origin Unicode Workbook Template. Researchers, engineers, and scientists use these files to save custom spreadsheet layouts, column headers, metadata, and pre-set analysis operations in Origin. This allows users to apply the exact same data formatting and mathematical processing to new datasets repeatedly.
You need Origin or OriginPro (version 2018 or newer) to natively open and utilize .otwu templates. The 'U' in the extension designates Unicode support, allowing the templates to handle international text characters properly.
The .otwu format is heavily restricted. It is a proprietary, closed file type controlled entirely by OriginLab. Sharing these templates with colleagues who lack a paid subscription is highly problematic. The format cannot be read by web browsers, standard text editors, or standard spreadsheet tools like Microsoft Excel.
To share the structure or associated data, users must extract the contents to accessible formats. The best conversion targets are XLSX for Microsoft Excel compatibility, CSV for raw text-based data transfer, or PDF for visual sharing of the workbook layout. Be aware that complex mathematical operations, embedded scripts, or live graph linkages unique to Origin will be lost during this export.
Standard online converters fail to process .otwu files because the format relies on undocumented, proprietary encoding. Often, only the original software can properly interpret the internal logic. Our system will inspect the file's internal architecture, and if our analysis detects supported underlying text or embedded metadata, viewing or conversion may still be possible without the expensive software.
Convert.Guru analyzes your OTWU file, detects the exact format, and lets you read the text inside.
If you want to convert OTWU file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use Origin or similar software from the "Scientific Workbook Template Storage" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to OTWU, try Origin or another comparable tool in the "Scientific Workbook Template 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 OTWU converter.
