I have thousand list coordinates from excel format (CSV file), its projection is Geographic WGS 84 (EPSG 4326) most of all. All of the coordinates are inserted manually from our surveyor teams. But we know that sometimes we make mistakes by putting wrong format coordinates, for example the correct coordinates is "6.504302, 112.786543" but they insert it as "6504302, -112786543" because of human errors. It's quite tiring to find the mistakes among thousands list excel cell and sheet, it also takes times too.
Are there apps, tools, or methods to find and replace the mistakes with correct values?
