Check CSV or TSV columns and parsing

Check file parsing

1. Import a CSV, TSV or delimited TXT file, or try the built-in sample.
2. If accents or columns look wrong, open reading settings: delimiter, encoding and header row. Analyse again.
3. Inspect structure and preview, then find a field or copy its name.

Example: semicolon-separated data

code;city;amount
0012;Lyon;15,50
0013;Brest;

Delimiter: semicolon
First row: headers
0012 remains text, including its leading zeros

Understand counts and exports

CSV values remain text: suggested types are observations, not conversions. Quoted separators and line breaks are supported. Blank rows count as records.

JSON and CSV exports describe the structure: fields, types and counts, not every data row. Search does not narrow exports. CSV exports protect field names that a spreadsheet could interpret as formulas.

Limits and privacy

Maximum 10 MB, 50,000 records, 500 fields and one million cells. Preview: up to 100 rows and 20 fields, cells shortened to 240 characters. Analysis stops after 30 seconds.

UTF-8, Windows-1252 and UTF-16 are available. Failed or cancelled analysis keeps the last successful result. No file is uploaded; download exports before leaving.
