Learn moreConvert an Excel file to CSV without breaking the data

The [Excel to CSV converter](tool:excel-to-csv) converts locally with explicit encoding and delimiter choices, and the [UTF-8 guide](guide:excel-to-csv-utf8) covers the pitfalls in detail.
Open solutionRemove duplicate CSV rows without damaging the source
Duplicates can be exact, partial, or caused by whitespace and letter-case differences. Choose the rule before deleting rows.
Open solutionClean messy CSV data before it reaches another system
Exports from different tools rarely match cleanly. Normalize whitespace and empty values before the next import.
Open solutionConvert CSV to Excel without formatting surprises
Excel can silently reformat numbers, dates, and leading zeros. The [CSV to Excel converter](tool:csv-to-excel) converts deliberately, and the [CSV cleaning guide](guide:clean-csv-data) shows how to keep values intact before import.
Open solutionConvert CSV rows into SQL you can review before running
