Private browser workflow

Clean and convert CSV and JSON data.

Profile, clean, combine, and convert CSV or JSON exports locally before importing them elsewhere.

Recommended order

From source files to a checked result

Use this workflow for private exports and operational data that need structural checks before entering another spreadsheet, database, or API.

Profile the source table to understand columns, blanks, and inconsistent values.
Clean rows and merge compatible exports while preserving an untouched source copy.
Convert the final table to the required CSV, TSV, or JSON format and inspect a sample.

Inspect column types, unique values, empty cells, ranges, and duplicate rows.

Trim fields and remove empty or duplicate rows from CSV and TSV files.

Combine multiple CSV or TSV files and align columns by their headers.

Convert quoted CSV, TSV, and JSON data without uploading it.
