Excel to CSV

Drop an .xlsx, pick a sheet, and Plotiq emits clean UTF-8 CSV — no mojibake, no BOM, no locale surprises. Fixes Excel's native "Save As CSV" quirks in one conversion.

Prepares Excel workbooks for Python, Pandas, BigQuery, or Postgres.

1. Upload an .xlsx or .xls file

Drop the workbook into the input pane. Both modern .xlsx and legacy .xls formats are supported.

2. Pick a sheet from the dropdown

Multi-sheet workbooks show every sheet. Switching sheets re-emits the CSV live on the right.

3. Copy or download the CSV

Output is UTF-8 without BOM — the universal encoding for Python, Pandas, BigQuery, and Postgres.

Why does Excel's own "Save As CSV" break non-ASCII characters?

Excel for Windows saves CSVs in the system code page (often Windows-1252), which corrupts accented letters, emoji, and non-Latin scripts. Plotiq outputs UTF-8 without a BOM — the universal safe encoding.

How do I convert a multi-sheet workbook to CSV?

Upload the .xlsx and pick a sheet from the dropdown. Switching sheets re-emits the CSV live. Download one CSV per sheet.

What happens to formulas in the CSV export?

Formula cells export using the cached value Excel was showing. Open and save the workbook once to make sure the cache is populated.

Are empty rows dropped automatically?

Yes — the "Drop empty rows" toggle (on by default) strips any fully-blank row, which Excel often leaves behind in its "used range".
