Sobre esta ferramenta

The CSV viewer opens a CSV file online so you can sort, search, and inspect it without a spreadsheet app. The table view supports clickable column sorting, full-file search, and pagination, while the column profiler tab shows each column's detected type, unique count, missing count, and sample values.

Sort any column (numeric-aware) and search across all cells

Para quem é

Useful for anyone who receives a CSV export and needs a quick answer: what columns exist, which cells are blank, and whether the file is worth cleaning or charting.

Como usar

Choose a CSV, TSV, TXT, or Excel (.xlsx, .xls) file (up to 5 MB) — it never leaves your browser.
Use Table View to sort columns and search within records; adjust rows per page (10–100).
Open Column Profiler to check types and missing counts per column.
Download the CSV when you need a copy, or continue in the Cleaner or JSON converter.

Exemplo

city,country,orders
Berlin,Germany,14
Paris,France,9
Munich,Germany,11
search: berlin → 1 of 3 rows

Searching for “berlin” keeps only rows containing it in any cell:

Formatos e fluxo

Accepted: .csv, .tsv, .txt with automatic delimiter detection; UTF-8 reading; Excel (.xlsx, .xls) workbooks open directly — pick a sheet if there are several.
Empty lines are skipped during parsing; blank cells display as null in tables.
Export: CSV download to your device.

Viewing is the inspection step. Once you understand the shape, clean messy values, check overall quality, or convert formats. Limpador CSV, Analisador, CSV para JSON.

Perguntas comuns

What is a CSV viewer?

A CSV viewer opens a comma- or tab-delimited file as a readable table so you can sort, search, and check its structure without a spreadsheet program. Datio's viewer adds a column profiler that shows each column's detected type, unique values, missing cells, and samples.

How do I view a CSV file online without Excel?

Open Datio's CSV Viewer and choose the file from your device — it is parsed locally, never uploaded. Sort any column by clicking its header, search across all records, page through results, and download a CSV copy whenever you need one. No signup or install required.

How can I see which cells are blank?

Open the Column Profiler tab: every column lists its missing-cell count, and blank cells display as null in the table. For file-wide totals, the Data Profiler reports the total missing-cell count plus a per-column breakdown. Analisador →

CSV Viewer or CSV Cleaner — what's the difference?

The Viewer inspects without changing anything: sorting, searching, and type checks. The Cleaner changes the data: it removes duplicates and blank rows, trims whitespace, and normalizes casing. Inspect first, then clean. Limpador CSV →

Limitações

The CSV & Excel Viewer is for inspection of one file at a time (up to 5 MB). It does not edit cells in place — use the Cleaner for deduplication and casing, or Transform & Filter for column transforms.
