+# Find The Nth Character Position In A File
+
+While trying to load a JSON file in a JavaScript program, I got an error
+message. The error message said that there was an issue parsing the JSON file
+at the 9010th character position in the file. Though highly specific, this
+didn't feel particularly actionable. I'm not going to count out 9010 characters
+in a massive JSON file.
+
+It turns out that Vim can help with this. After opening the file, I can then
+run this search:
+
+```
+/\%^\_.\{9010}/e
+```
+
+This will put my cursor right on the 9010th character.
+
+It matches on the first character position in the file (`\%^`), then it matches
+on _any single character or end-of-line_ (`:h /\_.`), and then it matches on
+that character class the number of times specified (`\{N}`) — in this case,
+9010 times. 
+
+Lastly, the second `/` marks the end of the search pattern and the `e` tells
+the search to place the cursor at the end of the match. Without the `e`, the
+cursor will be placed at the beginning of the match. For a match on thousands
+of characters, that's not too helpful.
