Abstract: A text editing method updates one or a plurality of historical files which store text data by historical data of edited results. The text editing method includes the steps of (a) developing, at a start of an editing, text data of a specified historical level in a text file format based on a specified historical file, (b) recording, at a time of text editing, historical information indicating correction contents of corrected text data for each record or each line of the text, and (c) extracting, at an end of the editing, the record or text in which the historical information is set, and reflecting the extracted record or text in the historical file.
