Extracting data from a spectrometer to Excel

AI Thread Summary
The discussion revolves around issues with converting data from the OceanView software used with the HR4000 spectrometer. The user encounters difficulties when saving files in the .ocv format after using a laser beam with gelatine sheets, resulting in unreadable data when attempting to extract it to Excel. In contrast, successful conversion was achieved using yellow light with a different solution. Participants suggest that the .ocv format may be proprietary, and emphasize the importance of selecting the correct file type for export. There are also indications that the .ocv file might be compressed, as suggested by its header, leading to recommendations to try opening it with compression software. The conversation highlights the need for clarity in file formats and conversion processes within the spectroscopy software.

Good morning,

I used the Laser beam with HR4000 spectrometer with Ocean View software when saving the files it is saved by (.ocv) format. when trying to extract information to excel I get some unreadable data like (bkg thin sheet gel.png) attached. I used the same instrument and software with the yellow light but used solution of the mix not gelatine sheets, and i was able to convert it using excel but with the laser and gelatine sheet this is what I got I could not convert it.
This is the link i used to convert the data

Please help.
Thanks

Just a guess, but .ocv sounds like "Ocean View," so it might be a proprietary file format from the company. To import into Excel, it has to be ASCII data, like the .csv (Comma Separated Values) mentioned in the link.

Hi Drclaude.
When I used the yellow light I was able to convert it to from .ocv format to excel from this link
https://www.chem.utoronto.ca/coursenotes/CHM317/pdfs/Import Spectrum to Excel.pdf
but when I used the laser beam I got this
213053-66087f6d9d1c248bf3b4f8d358006f23.png

So, I am confused why I was able to have the data when I used the yellow light but could not when using the laser beam

You have to make sure that you are choosing the right file type when exporting from the spectroscopy software.

In the spectroscopy software I only have one option of(.ocv) format nothing else.

If it worked for one it should work for the other - it's the same software, right? OceanView? On page 44 of the manual it has a picture of the dialog box, with "ascii" selected...
 
The PK at the beginning strongly suggests it is a compressed file. Have you tried opening it with a compression software?

Good catch! (I can't even read the screenshot!) That's the header for zip files; the initials of the inventor.
