Spire.PDF convert to Excel is cutting out Text as an image

[bunggotor]

I am using NuGet package FreeSpire.PDF (8.6.0, NuGet indicates it's the latest) for a desktop app written in C# .NET 4.6.1 to convert a single page PDF to Excel. I wish I can provide the file, but it has highly private data that I cannot share.

My original file had a few more color aspects to it (like orange used for shading). I got an updated file and it has grey instead of orange, and I think it's making it harder for the software to convert the PDF to Excel.

It creates a fairly close version, however there are some pieces of data which used to be text are now just being cut out as an image, and the image is just the text as an image. Therefore when I try to read the Excel file, it cannot see the image anymore (it used to be text).

So... I updated my app to .NET Core (7.0) and got the latest version of Spire.PDF. This appears to have addressed the table, but there is a lot more inconsistency with the new export which I think is because the PDF has a lot less contrast than it used to.

Are there settings/options I can use to try to cause more contrast? Or for it to take extra effort to try to figure out the text instead of cutting the text out as an image?
