Parsing data for operation in Excel

[artz]

Hi,

I am using a circuit simulation program called LTSPICE. It has an option to export chart data to a text file. Unfortunately, the format is not directly compatible with Excel. A snippet of the file output is shown below:

Freq. V(out)
1.00000000000000e-002 (-1.07460150501695e+000dB,1.70221075386850e+002°)
1.02329299228075e-002 (-6.74640008303624e-001dB,1.69991552342250e+002°)
1.04712854805090e-002 (-2.74683403826346e-001dB,1.69756559710614e+002°)
1.07151930523761e-002 (1.25267781027906e-001dB,1.69515961436982e+002°)
1.09647819614318e-002 (5.25212965403845e-001dB,1.69269617699112e+002°)
1.12201845430196e-002 (9.25151509702781e-001dB,1.69017384779520e+002°)
1.14815362149688e-002 (1.32508270979400e+000dB,1.68759114931987e+002°)
1.17489755493953e-002 (1.72500579066355e+000dB,1.68494656242269e+002°)
1.20226443461741e-002 (2.12491989944593e+000dB,1.68223852482718e+002°)
1.23026877081238e-002 (2.52482409777929e+000dB,1.67946542960527e+002°)
1.25892541179417e-002 (2.92471735341947e+000dB,1.67662562359300e+002°)
1.28824955169313e-002 (3.32459853104108e+000dB,1.67371740573617e+002°)
1.31825673855641e-002 (3.72446638214826e+000dB,1.67073902536292e+002°)
1.34896288259165e-002 (4.12431953400941e+000dB,1.66768868037971e+002°)

I would like to have 3 columns of data: Freq., Amplitude, and Phase. The Amplitude needs the dB removed and the Phase needs the ° removed. The parentheses also need to be removed. Also, having the data delimited by commas would be best. It would also be nice to have the data limited to 3 decimal points. The files are of variable length in rows.

Could anyone in the Forum help with a VBA macro that could do this processing?

Any help would be greatly appreciated.

Thanks,

Art

Do you really want VBA ??
Formulae can do this

Hi,
having the data delimited by commas would be best.
Thanks,
Art

Hi,

I'm also going to propose a formula solution, but needs to clarify, by the above, do you mean you want the results all in a Single cell per row ?

Hi Sandy,

This looks mostly right. Yes, VBA is preferred. I can hack at it but with cell formulas I have more difficulty.

Thanks,

Well, I guess you want the results in 3 Separate Columns, so I don't understand the "comma delimited" part...

Formula copied down and across:

Hi Michael,

Your formula works but I have 2 issues:

Excel will not allow me to truncate/round to 2 or 3 decimal places that your cell formula creates. Also, I have absolutely no idea what your cell formulas are doing, that why I prefer VBA.

Thanks,

Art

 

[sandy666]

This looks mostly right. Yes, VBA is preferred. I can hack at it but with cell formulas I have more difficulty.

this is not formula(s) but PowerQuery

 

[jtakw]

Check my formula in Post # 6, it should be producing the results you want.

 

[artz]

Hi jtakw,

Probably I missed something with the csv request. In a perfect world, I would be able to use Excel to open the txt file described in the snippet, format to 3 columns, and then ask to save in XL, csv, or txt format.

That's the cat's meow.

Thanks,

Art
