ExcelCollation&Correction (English Version) 2019/2/9 This application checks the data of two Excel files and modifies them if necessary. There is a button that collates common data columns as keys and whether they are the same. If they do not match, the application displays the number of lines, so please correct it manually. If they match, please specify each column to modify. There is a button to overwrite from the right one to the wrong one. There may be cases where the wrong file has a different order of collation and correction columns. In that case, the application has a button to find the correct data in the correction column of the wrong file and overwrite it based on the correct collation column and the correct modification column.
