Let's first open our InDesign document. In my example I plan to extract all the proper names that specifically occur in the footnotes.

Step 1 — Open your document in InDesign.

Running IndexMatic, I select the footnote paragraph style and go into the Single query mode. Here I will use the usual query /\m\w+/ in order to grab all words starting with a capital letter. Then, instead of building an index, I trigger a hit report:

Step 2 — Run IndexMatic and adjust your settings (scope, style, query, etc.)

In the Hit Report dialog, let's make sure the options Display stats and Sort by frequency are checked:

Step 3 — Generate a Hit Report.

IndexMatic might generate a large number of results, including unwanted entries (this depend on your document, your query, and your goal.) Edit the data in your text editor so that only the words and frequencies you want to visualize remain in the set:

Step 4 — Edit your data (remove unwanted entries, etc.)

Going back to InDesign, create a temporary document and fill a text frame with your word list. Note that words and frequencies are still formatted in a way that Wordalizer cannot properly parse:

Step 5 — Paste the list in a fresh text frame.

so we run a quick GREP command to replace multiple spaces by a colon punctuation mark:

Step 6 — Change multiple spaces into a colon separator.

Before you go further, make sure that the option Detect word list is turned on in Wordalizer's preference panel. (To check and/or change your preferences, run the script and click the gear icon.)

Step 7 — Activate the option “Detect word list” in Wordalizer's preferences.

Then, having your word list in the active document, run Wordalizer. In the Source panel, select the document icon and disable the language flag:

Step 8 — In Wordalizer, select the active document as source.

When the data are loaded in Wordalizer, adjust your settings as needed. If necessary, click the Boost low entry weights button to make low frequencies more perceptible:

Step 9 — Adjust the weights and your word cloud settings.

Finally, create the word cloud, and enjoy the result!

The final word cloud.
