The invention discloses a template merging method and device, and belongs to the technical field of information processing. The method comprises the following steps of: obtaining a first text extraction template and a second text extraction template; detecting whether fixed character fields, located at same character positions and having different contents, in the first text extraction template and the second text extraction template satisfy a merging condition or not; and if the detection result is positive, merging the first text extraction template with the second text extraction template to obtain a merged text extraction template. According to the method and device, the problems that the quantity of text extraction templates is relatively high and the application range of a single text extraction template is relatively small as text extraction templates in the prior art only replace digital character strings or letter character strings by variable character fragments are solved, and the effects of merging the first text extraction template and the second text extraction template, decreasing the quantity of the text extraction template, and enabling the merged text extraction templates to be larger in application range and higher in coverage rate are achieved.
