Open CSV Data Online
CSV stores rows as delimited text, but quoting, encodings and inferred types still need parsing. Anyfile registers the selected file with DuckDB-Wasm and returns bounded Arrow batches to the table viewer.
Choose a .csv fileYour file stays on this device
Anyfile reads only the local file you select. Parsing, decoding and rendering happen in this browser tab; the file is not uploaded to Anyfile servers.
What Anyfile can show
- Inferred columns and data types
- Paged rows from plain, gzip or Zstandard CSV
Limits and conditions
- Delimiter and type inference can misread irregular files
- CSV does not preserve formulas or workbook formatting

Common question
Can Anyfile open a very large CSV?
It avoids rendering every row at once, but parsing and queries still use this device’s memory.
