The invention belongs to the technical field of information processing, and particularly relates to a non-structured data and structured data mutual conversion processing method. The method comprisesthe steps of performing tag classification processing according to a tag realization function; for tags, performing field attribute and management attribute processing; combining to-be-structured datawith the tags, and creating a usage version template; according to the usage version template, converting the non-structured data submitted by a user into static webpage contents, and according to tag types, converting the tags into editable controls and converting the submitted data into structured data; selecting the usage version template to perform structured data online editing; and performing associated storage on the edited data and the corresponding template usage version. Through tag definition and template processing of non-structured data files and generation and conversion storageof non-structured data files, mutual conversion between the non-structured data and the structured data is realized, so that subsequent data analysis processing is facilitated. The method has relatively high application values.
