I know this question was already asked on here, but the answer from the link below did not work, at least on this QGIS, as no ASCII option was available when clicking on the files of type option.

QGIS Export Raster to asc

.asc is definitely there for you to choose (in Raster -> Conversion -> Translate (Convert Format)... -> Parameters tab -> Converted box -> ... button -> Save to File...). While not labeled as such, using an .asc extension produces a text file in Arc/Info ASCII grid format.

  • ok thanks, I will try that. – AQGIS Jan 31 at 10:16
  • It is not at all obvious that the menu for selecting the file format opens from the right side of the "Converted" box. The "Type" selection lets you to select the datatype (8 bit, 16 bit, 32 bit etc.). – user30184 Jan 31 at 10:21
  • @user30184 it is the same for all QGIS tools - so how is it not obvious? – Erik Jan 31 at 10:37
  • I would say that in Layer - Save as - [Format] the format selection is obvious. Also the old UI in wiki.tuflow.com/index.php?title=QGIS_Export_Raster_to_asc is much more clear with the "Output file" selection. For my mind is is not obvious that title "Converted" means "The name of the output file". – user30184 Jan 31 at 12:15
  • I agree with @user30184 and also found the current listing of file extensions without accompanying file format information unnecessarily confusing, particularly as other raster save options in QGIS 3.12ish used named formats rather than extensions. (Suggested a clarifying edit.) – Todd West Aug 25 at 15:48
