# AI Tools for Survey > AI Tools for Survey (https://www.aitoolsforsurvey.com) converts questionnaire > documents (Word/DOCX, PDF, Excel, TXT, Markdown) into LimeSurvey LSS files and > Qualtrics QSF files. The LSS export targets LimeSurvey 6.x — answer text is > written through the native answers + answer_l10ns localization structure, and > multiple-choice options are stored as subquestions the way LimeSurvey expects. > A legacy LSS export path supports older LimeSurvey versions. The QSF export > mirrors native Qualtrics export structure (SurveyEntry fields, Survey Blocks, > Survey Flow, Trash block, STAT element) and passes Qualtrics import > validation. Conversion is free to use online and includes a reviewable schema > step before export, plus machine-readable warnings for degraded features.
