CSViser is an online CSV validation and cleaning tool that fixes common data quality issues without writing code.

Upload a CSV (or XLSX/JSON) and get an instant RFC 4180 validation report with plain-English error explanations. Then fix detected problems in one click: remove blank rows, trim whitespace, unify NULL variants, normalize character encoding (Windows-1251/CP1252 โ†’ UTF-8), strip BOM, fix mixed line endings, convert delimiters (semicolon/tab/pipe โ†’ comma).

Beyond basic fixes: - Deduplication โ€” exact and fuzzy (Levenshtein) by all columns or a key column - Column type validation and conversion โ€” dates, numbers, emails, phone numbers (E.164), URLs, booleans, currencies - Search & replace โ€” substring, exact match, or regex with 24 built-in presets - Row filter โ€” delete rows matching a column value - PII anonymization โ€” redact or mask emails, phones, credit cards, SSNs, IP addresses - Split file โ€” by row count, file size, or column value; output as ZIP - Merge files โ€” inner, left, and full outer join by key column - Export โ€” CSV, XLSX, JSON, Markdown - REST API โ€” programmatic processing with Bearer token auth and webhook delivery

Free plan: all features, files up to 500 rows. Pro plan: unlimited.

Possible disadvantages of CSV Explorer

    As a cloud-based service, CSV Explorer requires a stable internet connection, which may be a drawback for users in areas with unreliable internet access.

    Uploading sensitive data to a cloud-based service might raise security concerns for some users, particularly if robust data encryption and privacy measures are not evident.

    Uploading CSV files to a third-party website may raise concerns about data security and privacy, especially for sensitive or confidential information.
  • File Size Limitations
    Web-based tools often have restrictions on the size of files that can be uploaded or processed, which could be problematic for users working with very large CSV datasets.
  • Limited Integration Options
    Compared to established platforms with extensive plugin ecosystems, a niche tool like this may have fewer integrations with other software or services for expanded functionality.
