Free CSV Analyzer
Upload a CSV file and get an instant breakdown — row and column counts, data types, missing values, duplicate rows, and numeric summaries. No account required.
Your file is analyzed in memory to produce this report and is not stored — no account is used, and nothing about the file is saved or used to train any model.
Analyze a CSV file instantly
Upload any CSV file up to 5 MB and get a full breakdown in seconds — no spreadsheet software, no account, no waiting.
What does this CSV analyzer show?
For every file: row count, column count, column names, and a detected type (number, text, or mixed) for each column, plus how many unique values it contains.
Check CSV data quality
The analyzer flags duplicate rows and counts missing values per column, plus suggests when a column stored as text is actually numbers, dates, or true/false values throughout.
Get insights from your data
Numeric columns get a real summary — minimum, maximum, average, and median, calculated directly from your file. An optional AI-written summary highlights what stands out in the data quality findings.
Turn analyzed data into dashboards and reports
This tool gives you a quick read on a single file. BI Studio is the full workspace for going further — dashboards, reports, and AI-generated summaries built from your real, connected data.
Frequently asked questions

Every row and column in your file, plus a detected data type (number, text, or mixed) and unique-value count for each column.
Can it find duplicate rows?

Does it calculate statistics for numeric columns?
Yes — minimum, maximum, average, and median for every numeric column, calculated directly from your file.
Is my CSV file stored anywhere?
No — it's parsed in memory for that one analysis and discarded. Nothing is saved or used to train any model.
