Document processing method and device, electronic equipment and storage medium

The invention provides a document processing method and device, electronic equipment and a storage medium. The method comprises the following steps: selecting a to-be-processed object in a first document in response to a first input, determining the confidentiality level information of the to-be-processed object, and encrypting the to-be-processed object; in response to the second input, determining a second document and acquiring confidentiality level information of the second document; comparing the confidentiality level information of the second document with the confidentiality level information of the to-be-processed object; and when the confidentiality level of the second document is higher than or equal to the confidentiality level of the to-be-processed object, decrypting the encrypted to-be-processed object, and writing the obtained to-be-processed object into the second document. The high-density and low-flow phenomenon can be effectively prevented, secret-related data leakage is avoided, and potent
