• Unfortunately not. Written form is the more "expanded" version of standard form, so I suppose instead of writing out "nine hundred sixty-seven" you could just simplify it to 967.

Generally, written form is the kind of thing you learn once and then never use again. It's just useful for learning to speak numbers.
• What is "fifty thousand, six hundred thirty-one" in standard form?

• Why don’t you write a comma after like 1,000 or 10,000 or 100,000 or 10,00,000
• So you can show where the thousands are or ten thousands or hundred thousands.
