Convert Excel to CSV or JSON, build XLSX from JSON, split sheets, merge workbooks or extract PDF tables online for free. Review headers, types and layout in the result.

PDF table extraction uses text positions and needs review. Workbook conversions do not guarantee original styling or complex formula results.
Read KitNelo data and privacy detailsChoose an XLSX workbook and export worksheet data to the supported CSV or JSON format. Inspect headers and value types in the result because workbook styling and complex formula results are not guaranteed to carry over.
Supply supported JSON table data and convert it into an Excel workbook for download. Open the XLSX output to confirm column names, row alignment and inferred value types before passing it to another spreadsheet workflow.
Load the workbook and use the sheet-splitting operation to separate its worksheets into exported files. Review the sheet names and content of each result, checking any formulas or references that depend on other workbook sheets.
Select the workbooks you want to combine and run the merge operation to produce an output workbook. Inspect sheet organization, repeated headers and important values afterward; original styles and complex formula behavior may not be preserved.
Choose a PDF containing table text and convert the detected table into an Excel result. Check each column and row against the source, since extraction relies on text positions and can misalign irregular table layouts.
Convert an Excel workbook into a PDF of rendered worksheet tables. Inspect each sheet for wide columns, wrapped cells and page boundaries. The export renders cell text, so advanced formatting and Excel print layouts may not be retained.
Open a CSV file and export it as an Excel workbook. Inspect headers, delimiter handling and values with leading zeros. Conversion changes the file format and does not reconstruct formulas or formatting missing from the CSV.
