From sketching your model and building an AI questionnaire to filling Google Forms in bulk and encoding data for SPSS — every step of a quantitative study on one platform, right in your browser.
Four tools, one seamless workflow
Model designer: Draw a structural model on the canvas, pick SmartPLS · SPSS · AMOS and read the full result tables on simulated data that fits your model.
AI questionnaire builder: Hand your model (or a JSON file) to the AI assistant to generate a Likert questionnaire laid out as Variable · Question · Source, then download it as Word.
Automatic form filling: Reads your Google Form’s structure, generates responses by answer ratio for choice questions, loads Excel for open-ended and Likert questions, then submits in bulk with live progress.
SPSS data encoding: Paste a Google Form link and the AI assistant gives every variable an SPSS-ready name and codes the answer choices as numbers. Download an Excel file with the encoded data and a Codebook sheet.
Who it’s for
Undergraduates writing a thesis: Build the model, draft the questionnaire and prepare SPSS data without installing any software.
Master’s and PhD students: Try alternative models and preview SmartPLS/AMOS tables before you go out and survey.
Lecturers and supervisors: Show how to read Cronbach’s Alpha, HTMT, R² and model fit on simulated data.
Survey teams: Test Google Forms, enter valid data from Excel and encode it quickly and correctly.
Key features
Measurement scales: Cronbach's Alpha, CR, AVE, KMO, Bartlett, loadings — laid out like the software’s own tables.
Generated by AI: Reads your model, builds a Likert questionnaire with suggested sources, downloads as Word.
Ready for SPSS: Names SPSS variables, codes choices as numbers, keeps open-ended answers, exports Excel.
Bulk fill & submit: Generates responses by ratio, loads Excel, submits in the background on our servers with a progress log.
How it works
Design the model: Build the structural model, constructs, items and paths on the canvas.
Build the questionnaire: Pass the model to the AI assistant to generate a survey questionnaire and download it as Word.
Collect & fill forms: Put the questionnaire on Google Forms, test it and enter responses in bulk when needed.
Encode & analyze: Prepare the data for SPSS, then run your SmartPLS / SPSS / AMOS analysis.
Frequently asked questions
What tools does The Light Data offer?
Four tools in one workflow: designing a research model and reading result tables on simulated data (SmartPLS/SPSS/AMOS), building Likert questionnaires with AI, filling Google Forms automatically from Excel, and encoding data for SPSS.
Can it fill Google Forms automatically from Excel?
Yes. The tool reads the form’s structure from its URL, lets you set answer ratios for choice questions and load Excel data for open-ended and Likert-scale questions, then you preview and submit in bulk with live progress tracking.
Is The Light Data free?
Model design, result tables and AI questionnaires are free. Submitting Google Form responses, downloading the full simulated dataset and exporting encoded files are paid in credits (1 credit = 1,000 VND), charged only when the task succeeds.
Do I need to install any software?
No. Every tool runs right in your browser — no need to install SmartPLS, SPSS or AMOS.
Is the simulated data real survey data?
No. The data the tool generates is simulated, for learning and illustrating models — it is not real survey data. Only fill Google Forms that you own or have permission to fill.
