Chart a spreadsheet without uploading it
How to use it
Import a spreadsheet, choose the fields and the chart type, and compare the chart with the original numbers. The table is read in the browser. NexTool does not upload it and does not store the chart. A chart can look smooth and still plot the wrong column. Read the axis labels and one known value before you export or screenshot. This is not a statistical report. Empty rows and text in a numeric column will change the picture. Clean the sheet in the Excel studio first if the table is messy.
The file stays in this browser. NexTool does not upload it and does not keep a copy after you leave the page. Download the result and check it before you send it on. If the tab runs out of memory, the job stops and the original is still the one on your computer.
