CSV Import & Export

M Chart supports importing and exporting chart data as CSV files.

CSV Controls

Exporting

Click the Export button below the spreadsheet to download the current chart data as a .csv file.

Click the Import button below the spreadsheet and select a CSV file from your computer. The data will replace the current spreadsheet contents.

By default, M Chart uses a comma (,) as the CSV delimiter. If your CSV uses a different delimiter (e.g. semicolons or tabs), you can:

Override per-import — A delimiter option appears on the import dialog, allowing you to specify a different character for that import.
Change the default — Set a site-wide default delimiter in Chart → Settings.

CSV Controls

The first row and/or first column of your CSV become the chart labels, depending on your data format. See Creating a Chart for how label detection works.
Values with currency symbols ($, £) or unit suffixes (%, °C, K, M, B, T) are parsed correctly — the symbol is preserved in tooltips while the numeric value is used for the chart.
