This page is designed to help you find out whether TableRune is good and if it is the right choice for you.
Every file you open in TableRune stays on your own computer. Importing, cleaning, reshaping and charting all happen there, inside your web browser. Your data is never sent to a server, and we never receive it.
For financial and research analysts, accountants and consultants bound by confidentiality or data-handling agreements, that removes a familiar problem: no cloud copy of a client dataset to protect and no outside processor to disclose. There is simply no upload step.
Open CSV, Excel, ODS and Parquet files. Fix capitalization, dates, emails and blanks, remove duplicates, split or combine columns, then filter, sort, pivot, merge and compare files from simple menus. Every step is saved and can be reused on next month's file.
Free handles up to 500,000 rows with every cleanup tool, charts, 3 saved workflows and CSV or Parquet export. Pro raises the limit to 10 million rows and adds chart export and unlimited workflows. Team adds seat management. Desktop Chrome or Edge.

No upload
Everything runs on your own computer, in your browser. Your data is never sent to a server, and we never receive it.
TableRune never uploads your data. Opening, cleaning, reshaping and charting a file all happen on your own computer, inside the browser you already have. That is not a privacy policy, it is how the product is built: there is no upload step to opt out of.
For anyone working under a confidentiality or data-handling agreement, that removes the question of where the client's data went. It also means there is no upload cap: files of up to 500,000 rows on the free plan and 10 million on Pro, limited only by your plan and your computer's memory.
Every change is recorded as a step you can read, undo, save and run again on next month's version of the same file.
Against cloud spreadsheet and data tools, your file simply never leaves your machine, so the confidentiality question never comes up.
Against Excel, TableRune is built for the files that make Excel slow or that it cannot open at all, up to 10 million rows on Pro, and every cleanup is a saved step you can rerun on the next file instead of redoing it by hand.
Against local desktop data tools, there is nothing to install, which matters when your work laptop is managed by IT. Everything works from simple menus with no code to write, and there is a Team tier with central seat management.
Solo analysts and small firms, roughly one to fifty people: financial and research analysts, accountants and consultants. The common thread is that they handle confidential client data in files too big for Excel to work with comfortably, and they are not allowed to upload that data to a cloud tool.
A secondary audience is anyone who simply does not want their spreadsheets sitting on someone else's server.
TableRune started from a narrow observation: the people holding the most sensitive data often have the weakest tools for big files. Excel slows to a crawl or refuses the file, and the convenient web tools that can handle it ask you to upload it first, which a confidentiality agreement does not allow.
So we built a workspace that runs in the browser but does all of its work on your own computer, so the convenience of a web tool does not cost you custody of the data. Every cleanup became a recorded step from the start, so the work can be checked, undone and repeated on the next file.
