Upload DOCX, TXT, or PDF survey documents and get ready-to-import LSS files with preserved question structure, answer options, and survey logic.
Select your survey document and start the AI-powered conversion process.
Deep Parse extracts a reviewable schema in stages (groups, questions, options, logic), confirms it automatically, and exports a LimeSurvey 6-ready .lss file.
Advanced AI algorithms identify and extract survey questions automatically
Recognizes multiple choice, rating scales, and text input fields
Maintains skip logic, branching, and conditional questions
Generates LSS files for direct import into LimeSurvey

AI Tools for Survey converts Word, DOCX, PDF, TXT, and Markdown survey documents into LimeSurvey LSS files, with the current default export aligned to LimeSurvey 6 answer localization structure.
Default LSS export targets LimeSurvey 6.x style imports and writes answer text through answers plus answer_l10ns rows.
The export uses DBVersion 636 for the modern LSS path, matching the LimeSurvey 6.15 compatibility target used in production validation.
A legacy LSS export path remains available for older LimeSurvey installations that expect answer text directly in answers.answer and answers.language.
The Deep Parse workflow creates a reviewable schema before generating the final .lss artifact.
The LSS Inspector can be used after conversion to check question text, answer options, and import readiness before launching a survey.
Import the generated .lss file into a non-critical LimeSurvey project first.
Confirm that question groups, question text, subquestions, and answer options appear after import.
Use LSS Inspector or LimeSurvey preview to compare the imported survey against the original document.
For older LimeSurvey versions, choose the legacy export path instead of assuming a LimeSurvey 6 file will import cleanly.
The LimeSurvey 6-compatible path is validated for answer option preservation, but every converted survey should still be reviewed before field launch.
Older and legacy LimeSurvey versions can require the legacy LSS structure; the modern export is not intended for every historical database version.
Complex skip logic, quotas, custom themes, and platform-specific settings may still require manual review in LimeSurvey.
Yes. Upload a Word, DOCX, PDF, TXT, or Markdown survey, review the extracted schema, then export a LimeSurvey LSS file for import and validation.
The default LSS export is designed for LimeSurvey 6.x style imports and uses DBVersion 636 with answer_l10ns for answer text preservation.
Check question groups, question text, answer options, subquestions, and any logic or branching before launching the LimeSurvey project.
Not by default. Older LimeSurvey installations may need the legacy LSS export path because their importers can expect answer text in older table fields.

LSS (LimeSurvey Structure) is the native file format used by LimeSurvey, an open-source survey platform. LSS files contain all survey elements including questions, answer choices, display logic, and survey settings. They can be directly imported into LimeSurvey for immediate use.
Our AI can convert various question types including multiple choice, single choice, text input, numeric input, rating scales, matrix questions, and yes/no questions. The system also preserves skip logic, branching conditions, and question dependencies where clearly defined in the source document.
Yes, LSS files can be edited in several ways. You can import the file into LimeSurvey and use its built-in editor, or you can use our LSS Inspector tool to review and validate the structure before importing. Advanced users can also edit LSS files directly as they are XML-based.
Our AI is designed to handle basic to moderate survey logic including skip patterns and conditional questions. For complex logic with multiple dependencies, we recommend reviewing the converted file using our LSS Inspector tool and making manual adjustments in LimeSurvey if needed.
Yes, our AI supports surveys in multiple languages. The system can process documents in various languages and preserve the original text in the LSS output. However, accuracy may vary depending on the language and document structure.
If you're not satisfied with the conversion results, try these steps: 1) Use our LSS Inspector to identify specific issues, 2) Check if your source document has clear question structure, 3) Consider reformatting your source document for better AI recognition, 4) Contact our support team for assistance with complex surveys.
