CSV Tools

Convert, clean, profile and analyse CSV files locally in your browser.

CSV Column Profiler Profiles each column for inferred type, completeness, distinct values and numeric range.
CSV Column Selector Keeps or drops named columns, returning them in the order you listed.
CSV Delimiter Converter Rewrites a delimited file with a different separator, re-quoting fields as needed.
CSV Diff Compares two files on a key column and reports added, removed and changed values.
CSV Duplicate Remover Removes repeated rows, matching either on the whole row or on named key columns.
CSV Header Cleaner Rewrites column names to a consistent naming convention and resolves duplicates.
CSV Join Joins two delimited files on a shared column, with a left or inner join.
CSV Row Filter Keeps only the rows where one column matches the condition you set.
CSV Sorter Sorts rows by a named column, treating numeric columns as numbers rather than text.
CSV Splitter Splits a file into fixed-size chunks, repeating the header on every part.
CSV to HTML Table Converts delimited rows into semantic HTML table markup with escaped values.
CSV to JSON Converts delimited rows into an array of JSON objects keyed by the header row.
CSV to Markdown Table Converts delimited rows into a GitHub-flavoured Markdown table.
CSV to SQL Insert Generates INSERT statements from delimited rows, quoted for the dialect you pick.
CSV to XML Converts delimited rows into well-formed XML with one element per row.
CSV Transposer Swaps rows and columns so a wide layout becomes a tall one, or the reverse.
CSV Validator Finds ragged rows, duplicate column names and unnamed columns, and reports where they are.
CSV Viewer Renders a delimited file as a readable table, including quoted fields and embedded line breaks.
TSV to CSV Converts tab-separated text to comma-separated, quoting values that need it.
