I've made a new version. Now the user can prepare a list of the fonts to be changed, say in Excel (optionally), and save it as CSV-file which will be used by the script, or you can edit it directly in the CSV-file using a plain text editor like Notepad (PC) or TextEdit (Mac).

I've moved this thread from the (fairly quiet) Type & Typography since this isn't really a question about type, but more of a question about how to use Adobe software. Thus it is now in a product-specific support forum. I would recommend you create a post in the Illustrator forum as well since the answer is likely to be different for each software.
That being said, perhaps this would be a question for Illustrator Scripting or InDesign Scripting, but I'm not familiar enough with either of them to know for sure. 
For InDesign documents you can use Type>Find Font... (not Find/Change) which lets you change a document's fonts with the option of updating any styles that use the font with one click. It is certainly scriptable and one likely exists, so ask in the scripting forums.
It looks like a very interesting idea for making a script.
I wrote a quick & dirty script for changing fonts which should be used together with my new Batch processor.
Here I posted the script and before and after sample documents (ver. CC 2017).
In the future I'm going to make a more user friendly version so the user could prepare a list of the fonts to be changed, say in Excel (optionally), and save it as CSV-file which will be used by the script. But so far you have to make minor edits to the script:
At the very beginning you'll see the first variable which is the array of arrays containing the names of the fonts in the format
[ "Find this", "Change to this" ],
Here I used the fonts installed with InDesign to make sure that everybody have them and can test the script using my sample.
The left element is 'Find this', the right one is 'Change to'.
The family name and font style should be separated by a tab: either \t or by actual tab (by hitting tab on the keyboard)
The find-change pairs (the elements of array) are separated by commas so make sure that you won't leave a comma after the last element (see the screenshot above).
Then you can select the script in the Batch processor like so:
The 'change fonts' script does the following:
- changes the fonts in all the paragraph styles
- changes the fonts in all the character styles
- changes the fonts applied as a local formatting in the same way as the 'find this font and change to that font' feature works in the Find-Change Text dialog box. Note: to illustrate this point, the first paragraph in my sample is set to Letter Gothic Std and Minion Pro - Bold, Italic and Bold Italic.
The script changes Minion Pro - Bold, Italic and Bold Italic to Myriad Pro (Letter Gothic Std obviously is left unchanged).
Before
After
Here's the script:
var fontList = [
["Minion Pro\tRegular", "Myriad Pro\tRegular"],
["Minion Pro\tBold", "Myriad Pro\tBold"],
["Minion Pro\tItalic", "Myriad Pro\tItalic"],
["Minion Pro\tBold Italic", "Myriad Pro\tBold Italic"]
];
main();
function main() {
try { // if something goes wrong in the try-catch block, the batch processor won't stop here. It will log the error message and continue further
var newFont, paragraphStyle, characterStyle,
doc = app.activeDocument, // The frontmost document
paragraphStyles = doc.allParagraphStyles,
characterStyles = doc.allCharacterStyles;
// Change in paragraph styles
for (var p = 1; p < paragraphStyles.length; p++) {
paragraphStyle = paragraphStyles
;
newFont = getNewFont(paragraphStyle.appliedFont.name);
if (newFont != null) {
paragraphStyle.appliedFont = newFont;
}
}
// Change in character styles
for (var c = 1; c < characterStyles.length; c++) {
characterStyle = characterStyles
; newFont = getNewFont(characterStyles
.appliedFont + "\t" + characterStyles .fontStyle); if (newFont != null) {
characterStyles
.appliedFont = newFont; }
}
for (var i = 0; i < fontList.length; i++) {
var changed;
app.findTextPreferences = app.changeTextPreferences = NothingEnum.NOTHING;
app.findTextPreferences.appliedFont = fontList[0];
app.changeTextPreferences.appliedFont = fontList[1];
changed = doc.changeText();
app.findTextPreferences = app.changeTextPreferences = NothingEnum.NOTHING;
}
}
catch(err) { // if an error occurs, catch it and write the document's name, error message and line# where it happened into the log
gErrorLog.push(doc.name + " - " + err.message + ", line: " + err.line);
}
}
function getNewFont(oldFontName) {
var newFont = null;
for (var p = 0; p < fontList.length; p++) {
if (oldFontName == fontList
[0]) {
newFont = app.fonts.itemByName(fontList
[1]);
if (!newFont.isValid) {
newFont = null;
}
break;
}
}
return newFont;
}
Hope this helps.

Hi Uwe,
I do use them in the script.
Regards,
Kasyan
I think my approach is quite safe: with the 'Backup original documents' check box ON, the batch processor never overwrites the originals, even if you run the script many times.
The screenshot above illustrates what happens after running it 5 times:
Backup_Test-Before.indd -- is the original version
Test-Before.indd -- is the latest version
Backup(X)_Test-Before.indd -- intermediate versions

Hi Kasyan Servetsky
Thanks for answering.
I only have otf versions of Gotham installed.
Added this line to the csv-file but is not working neither:
Gotham\tMedium Helvetica\tRegular
Gotham (T1)\tMedium Helvetica\tRegular
So that was not the problem. Sorry.
Any other ideas?
Br, Fredrik
Ah, thanks for look ing into this.
Well most if the script works perferct anyway.
Cheers, Fredrik
