Intouch LGH File to CSV File
Convert .lgh files generated by Wonderware InTouch to .CSV


We have .lgh and .idx files those generated by Wonderware InTouch and We need to read them with Excel.

any easy idea that can help me to convert them to .CSV file?

I already found something from The InTouch books (Start > Programs > Wonderware> books) includes InTouch Data Management Guide, and chapter 11, starting on page 239 walks through several examples of how to do this. but I couldn't make it work.

You should take a look at LGH File Inspector by WorkSmart Automation. It reads Wonderware LGH files and can export to CSV and Excel.

XLReporter, which has been used in industry since 2001, converts LGH files to csv and Excel as well.

Hi buddy, what you mentioned can be resolved by InTouch Histdata Application accessed by DDE. You can find the words in manual.

I've developed a software to handle this problem, if you also cannot make it please email me.
