About this CSV hub
This hub bundles high-intent CSV workflows—convert to Excel or JSON, build PDF tables, emit SQL inserts, export XML or Markdown, merge batches, split oversized files, sort and filter, dedupe rows, preview grids, tweak columns, repair escaping, or diff two datasets. Open a tool, upload or paste, get a downloadable result.
Very wide files stress browser memory—sample or split first when approaching millions of rows. Pair with our JSON tools hub when you need formatters, validators, or JSON → CSV flattening alongside these spreadsheet-style tasks.

Frequently asked questions
- What can I do with these CSV tools?
- Convert to Excel, JSON, PDF, SQL, XML, or Markdown; merge or split files; sort, filter, and remove duplicates; view as a table; add or remove columns; fix quoting; compare two CSVs.
- Why does Excel mangle accents after CSV export?
- Excel sometimes guesses the wrong code page on double-click open. Prefer UTF-8 exports from our tools and import via Data → From Text/CSV with explicit encoding when teammates use Windows Excel.
- What CSV options are supported?
- Common delimiters (comma, semicolon, tab, pipe), encodings such as UTF-8, Windows-1252, and ISO-8859-1, and first row as header where applicable. Many tools auto-detect delimiter and encoding.
- Can I merge multiple CSV files?
- Yes. Use CSV merge to combine files with optional header handling. It runs locally and keeps your data private.
- Is there a practical file size limit?
- Very large files may be slow. For most tools, files under about 50MB work best.
