Re: Counting occurrences of specific characters In a document
a cheat.. you will create 2 copies of the data. $Start_size := length(Imported_Text) $Removed:=replace string(Imported_Text;Char(13)) $Removed_Size:=$Start_Size - Length($Removed) $Removed_Size = number of characters (returns) replaced > Thank you Cannon, > > Progress indicator is not the only reason we need to know number of > rows in advance.

Re: Counting occurrences of specific characters In a document
sounds like you are mainly interested in text data. you could try https://github.com/miyako/4d-plugin-xlsxio which converts XLSX to JSON. for XLS this might work https://github.com/miyako/4d-plugin-free-xl miyako ** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **
Re: Counting occurrences of specific characters In a document
If the only reason you need to know the number of rows beforehand is to help in showing a progress indicator, you could use the file size and current parse position instead -- Cannon Smith > On Nov 8, 2017, at 6:42 PM, rooftop99--- via 4D_Tech <4d_tech@lists.4d.com> > wrote: > > We are working with large Excel documents which contain upwards of 750K rows > and we need to import each row into a 4D application to create records.
