- Quick sanity checks before CSV imports (does the header have the expected width?)

How to use

- 2Click Count rows & columns.
- 3Use the result as a quick sanity check before importing elsewhere.
Common mistakes
- Assumes comma-separated values (not semicolons or tabs). Use the Delimiter Detector first if unsure.
- Does not handle quoted commas like: "ACME, Inc" (it will count as extra columns).
- Blank lines are trimmed, so pasted spacing can change the row count.
