In your dataset, make sure that strings exist only in the first row, which becomes the header with the variables names. Otherwise, only numbers are allowed (if a string appears from row 2 onwards, SmartPLS cannot read the dataset). Note: This is in almost all cases the reason when you encounter a problem with the data import in SmartPLS 3.
SmartPLS 3 allows you to import data file in the following format:
- comma separated value files (.csv)
- text files (.txt), which, for example, use a tab to separate the data points per row
Data Preparation in Excel or SPSS
For the data preparation, use a spreadsheet application such as Microsoft Excel or a statistical software such as SPSS. Spreadsheet applications and statistical software packages offer options to save the data in the .csv or .txt file format. Please take a look at some sample data files, which you can directly import into a SmartPLS 3 project. You may download and open these files with a text editor program and inspect how the data in the file looks like. Note: When using SPSS, you may need to switch of "labels" before saving the data in the .csv or .txt file format.
Use more memory for large data files
If you use large data files, you should use SmartPLS with more memory on your computer device.
