I have a set of data in CSV format where the first, second and third columns are Point #,Coord of X and Coord of Y respectively (in UTM Zone 51N). Then I added a delimited text layer in QGIS 3.16.5 and imported my CSV file there, setting the correct CRS to UTM Zone 51N as well as the correct geometry definition for the X & Y fields.

Now, when I try to export the newly added layer, I set the format to CSV and set the CRS to WGS84 (since I want it to convert from UTM Zone 51N to WGS 84), set the geometry to AS_XY and then clicked "OK".

When I opened the outputted CSV file, it turns out it created 2 new columns for the supposedly new converted WGS84 coordinates but the result is far from the actual value of what is really the correct coordinate.

I followed every YouTube tutorial but my QGIS is just converting it wrong. How or where in the process did I get it wrong?

    Please provide exemplary coordinates after export, as well as the EPSG-codes you used. – Erik Mar 01 '22 at 13:45

    This appears to be a duplicate of the most common question here (QGIS flavor). When you "set the CRS to WGS84", you likely clobbered the correct spatial reference. Instead, you want to set to the actual PCS, then project it to WGS84 decimal degrees. – Vince Mar 01 '22 at 15:46
  • What do you mean by exemplary coordinates? I'll try to look on the EPSG-codes tomorrow, im currently resting now. Thanks – MarkLawrence_1993 Mar 01 '22 at 15:47
  • How do i do that? The PCS to project to WGS84?...and what is PCS? – MarkLawrence_1993 Mar 01 '22 at 15:50
  • PCS is short for Projected Coordinate System. The EPSG code for UTM 51N in WGS84 is EPSG:32651, according to this website. – L. Lucchese Mar 01 '22 at 16:13
  • Ok thank u for providing the meaning of that acronym. But my problem still Exist. Still how do i solve it? – MarkLawrence_1993 Mar 01 '22 at 21:48
  • @Erik the EPSG code to UTM Zone 51N is EPSG:32651 – MarkLawrence_1993 Mar 01 '22 at 21:49
  • When you import the points: are they in the correct location on the globe (add a basemap to check)? If so, please describe your workflow a bit more detailed: where do you "set" the CRS?
