Database export analyst
Preserve padding, empty final fields and literal backslashes.
Import plain TSV containing tabs, quotes, comma cells and a trailing empty field.
Every selected source cell remains and no escape sequences are guessed.
TSV to CSV Converter

- Review errors and compare the output before replacing source data.
Choose your path
Built around the job you need to finish
Convert deliberately selected plain or quoted tab-delimited records into comma-delimited CSV without silently trimming fields or losing empty cells.
Spreadsheet interoperability developer
Choose the correct quoted-tab grammar and import policy.
Switch to quoted tabs for embedded tabs/newlines; test malformed quotes and formula rejection.
Dialect mismatch produces actionable errors and formula changes require opt-in.
Mobile data-cleaning reviewer
Save bounded conversion evidence without overwriting CSV/JSON work.
Run TSV in Format and Clean Data, save its three Project fields and reopen evidence.
Only current valid results are saved to the existing TSV-specific contract.
Authoritative checks for this tool
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.

How it works
Updated August 2026Select the source dialect
Plain mode uses physical lines and tabs, keeping quotes and backslashes literal. Quoted-tab mode explicitly adopts CSV-style quoting for embedded tabs and line breaks. Empty/headerless data are supported extensions, not strict IANA TSV conformance.
Validate every record
No trimming or type inference is performed. Blank-record skipping and missing-cell padding require explicit choices; extra fields are always refused. One leading BOM is treated as a file marker and disclosed.
Review and save a current export
All selected records remain in comma-delimited output. Header choice affects preview, not record inclusion. Formula policy applies to every text field. Explicit Project save writes the existing TSV source, output and status fields only.

Common Mistakes to Avoid
Common Mistakes to Avoid
Assuming all TSV exports use the same quoting
Select the actual source dialect; plain mode does not decode quoted or backslash-escaped cells.
Trimming data before conversion
Keep meaningful padding and trailing tabs; use explicit cleanup only after reviewing the data.
FAQ
Use plain tabs when quotes and backslash sequences are literal text. Select quoted tabs only when the export uses CSV-style quotes and doubled quotes around embedded tabs or newlines. No dialect is guessed.
No trimming or numeric inference is performed. Trailing empty fields remain. Spreadsheet applications may still infer types; import sensitive columns as text.
Only the preview interpretation. With no header, display column names are generated but not added to CSV. Every retained source record is exported.
Unequal widths are refused unless missing-cell padding is chosen; extra cells are never dropped. Formula-like text can be preserved with warning, prefixed with an apostrophe or refused. Prefixing changes values.
Yes, explicitly save a current successful result with source/output each at most 100,000 characters. The three TSV fields do not overwrite CSV-to-JSON or JSON-to-CSV fields. Conversion supports 5,000 data rows, 200 columns and 100,000 cells; preview is bounded.
