The LSS Inspector validates a LimeSurvey .lss file before import: it checks question groups, question text, subquestions, answer options, and logic so import problems surface before they reach LimeSurvey.
An LSS file is an XML dump of LimeSurvey database tables: surveys, groups, questions, subquestions, answers, and their localization tables.
LimeSurvey 6 stores answer text in answer_l10ns rows and multiple-choice options as subquestions; the inspector understands both modern and legacy layouts.
LimeSurvey answer codes are limited to 5 alphanumeric characters; oversized codes are a common cause of import failures.
The inspector reports questions, groups, answer options, and logic rules found in the file.
Run the .lss file through the inspector before importing it into LimeSurvey.
Confirm the question and group counts match the source questionnaire.
Check that every choice question lists its answer options or subquestions.
Import into a non-critical LimeSurvey project and preview the survey.
The inspector validates file structure and content; it cannot guarantee how a specific LimeSurvey version renders every question type.
Server-side import limits (PHP upload size, database constraints) are outside the file itself.
Themes, quotas, and site-specific plugins are not part of standard LSS validation.
Upload the .lss file to the LSS Inspector. It lists questions, groups, answer options, and logic, and flags structural problems before LimeSurvey import.
A frequent cause is answer codes longer than the 5-character limit of the LimeSurvey answers.code column, or options placed in the wrong table for the question type.
In LimeSurvey, multiple-choice options must be stored as subquestions, and answer text lives in answer_l10ns on LimeSurvey 6. Files that put options only in the answers table lose them on import.
Yes. It reads the LimeSurvey 6 layout (answers plus answer_l10ns, subquestion-based multiple choice) as well as legacy single-table layouts.
The LSS Inspector analyzes and validates LimeSurvey LSS files to ensure they contain correct questions, answer options, and survey logic. It provides a readable view of the survey structure, identifies potential issues, and helps ensure quality before importing into LimeSurvey.
The Inspector can detect various issues including malformed questions, missing answer options, broken logic conditions, invalid question codes, structural inconsistencies, and formatting problems. It provides detailed reports with specific recommendations for fixes.
Yes, the LSS Inspector can analyze LSS files from any source, whether they were created by our converter, exported from LimeSurvey, or generated by other tools. It works with standard LSS file format specifications.
Inspection reports provide comprehensive analysis including question-by-question breakdown, logic flow visualization, error highlighting, and actionable recommendations. Reports can be viewed online or exported for sharing with team members.
Currently, the Inspector identifies and reports issues but doesn't automatically fix them. This ensures you maintain full control over your survey content. We provide clear guidance on how to resolve identified issues manually.
The Inspector can handle LSS files of various sizes, from simple surveys to complex multi-section questionnaires. Very large files may take longer to process, but there's no strict size limit for inspection.
