About This Tool
CSV (Comma-Separated Values) is the universal text format for data interchange. JustConvert's Excel to CSV tool extracts all rows and columns from your .xlsx or .xls workbook and writes them into a clean, UTF-8 encoded CSV file that any application can read — from databases and analytics tools to Python scripts and R statistical software.
This is especially useful when you need to import Excel data into a CRM, send it to an API, load it into a database, or process it with data analysis tools. CSV is lightweight, human-readable, and works on every platform.

Why every import form asks for CSV
CRMs, e-commerce back-ends, payroll systems, email marketing tools, and bank upload portals almost universally ingest CSV rather than Excel files, because CSV is plain text: no formulas to evaluate, no macros to distrust, no version differences to handle. Converting your working spreadsheet to CSV is usually the last step before a bulk import — contacts into a CRM, a product catalogue into a store, transactions into accounting software. The output here is UTF-8 encoded, so names and text in Hindi, Tamil, or any other script survive the trip.
What to check before you export
CSV keeps values only, so know what gets left behind: formulas are replaced by their current results, formatting and colours disappear, and each sheet becomes its own file (multi-sheet workbooks download as a ZIP of CSVs). Two pre-flight checks prevent most import failures: make sure the first row contains clean column headers the target system expects, and format date columns explicitly as text in the pattern the importer documents — date ambiguity (01/02 as 1 Feb or 2 Jan) is the single most common cause of a rejected upload.

Upload your .xlsx or .xls file above and click Process. The converted CSV file will be ready to download instantly.
Can I convert a multi-sheet Excel file to CSV? expand_more
When an Excel file has multiple sheets, each sheet is exported as a separate CSV file, packaged into a ZIP archive for download.
Will formulas in Excel cells be preserved in the CSV? expand_more
CSV stores only values, not formulas. The calculated result of each formula is preserved, but the formula itself is not included in the CSV.
What encoding does the output CSV use? expand_more
The output CSV uses UTF-8 encoding, which correctly represents all characters including accented letters, currencies, and non-Latin scripts.
What is the difference between CSV and XLSX? expand_more
CSV is a plain text format containing only raw data values separated by commas. XLSX is a binary format that also stores formulas, cell formatting, charts, and multiple sheets. CSV is best for data interchange; XLSX is best for spreadsheet work.
