CSV Row Counter

Count rows, columns, and cells in a CSV file

Count the rows in a CSV file without opening it in a spreadsheet. Upload the file and get the record count, the number of columns, and a preview of the first rows so you can confirm the file parsed the way you expect.

Counting lines is not the same as counting records. A single CSV value is allowed to contain line breaks when it is quoted, so a file with 1,000 records can easily have several thousand physical lines. Tools that count newlines — including wc -l and most text editors — report the wrong number. This counts parsed records.

It is also a fast sanity check before an import: confirm a file is not truncated, verify a split produced the row counts you expected, or check a total against what the source system reported.

How to Use

  1. Upload your CSV file or paste CSV data
  2. Read the row, column, and cell counts
  3. Check the preview to confirm the file parsed correctly
  4. Use the counts to verify an import, a split, or an export

Features

  • Accurate record count that respects quoted line breaks
  • Column count and header list
  • Empty cell statistics to spot gaps in the data
  • Preview of the first rows to confirm correct parsing
  • Auto-detects comma, semicolon, tab, and pipe delimiters
  • Runs entirely in your browser — no upload, no row limit imposed by a server

Use Cases

  • Verify an export contains the number of records you expected
  • Confirm a file was not truncated during a download or transfer
  • Check row counts after splitting or merging files
  • Reconcile a file against a total reported by another system
  • Quickly size a file before choosing how to process it

Frequently Asked Questions

Why does this differ from the line count in my text editor?

Because a quoted CSV value can legally contain line breaks. An address field spanning two lines is one record but two physical lines, so newline-counting tools such as wc -l overcount. This parses the CSV and counts actual records.

Does the header row count as a row?

No. The header is reported separately as the column list, so the row count reflects data records — which is normally the number you actually want.

Can I count rows in a very large file?

Counting runs locally, so the limit is your device memory rather than a server cap. Extremely large files may be better split first.

Does it count columns too?

Yes, along with the header names and empty-cell statistics, which is a quick way to spot a column that is unexpectedly sparse.

Does it work with semicolon or tab-separated files?

Yes. The delimiter is auto-detected, so European semicolon exports and tab-separated files count correctly.

Is my file uploaded?

No. It is parsed in your browser and the contents are not sent to the app server.
