Does it remove spaces between words?

No. Trim only removes spaces at the very beginning and end of each string or line.

Why is trimming important for data?

Computers treat "email@test.com" and " email@test.com " as different. Trimming avoids mismatches.

Is this safe for customer databases?

Yes. All processing is local; nothing is sent to external servers.

Trim and CSV or JSON formats?

Trimming each line is safe for CSV (removes stray spaces in cells). For JSON, trim only if you have accidental spaces; valid JSON keys/values are not modified.
