Data processing method and device and readable medium

The embodiment of the invention provides a data processing method and device and a readable medium. The method comprises the following steps: acquiring first target data of a preset first type added in first data of the preset first type, converting the first target data into second target data of a preset second type, and adding the second target data into the second data of the preset second type. Therefore, when the second data is obtained by converting the first data, or when the first data is obtained by converting the second data, after the preset first type of data is added into the first data, the added data is automatically converted into the preset second type of data, and the preset second type of data is added into the second data, so that automatic linkage between the first data and the second data is realized, the problem that the content of the first data is inconsistent with the content of the second data after the first data is changed is avoided, the data does not need to be converted again
