Private, local-first data tools
Paste delimited text or open a TXT file, confirm how the columns are separated, and download a clean CSV without uploading the data.
The parser runs off the main thread. Once loaded, you can search, sort, validate, repair and export without an account.
What this tool does
The converter reads plain text in the browser and detects comma, tab, semicolon or pipe separators. You can correct the delimiter, header and encoding before exporting the parsed table as a standard CSV, so quoted punctuation and multiline values are handled as fields rather than changed with a global text replacement.
Local files are read by a dedicated browser worker and are not uploaded to an application server. File contents and filenames are not included in analytics events. Loading a public URL is an explicit direct request from your browser and may fail when the remote server blocks CORS.
Use text with consistent columns separated by tabs, commas, semicolons or pipes. Free-form paragraphs do not contain enough structure to infer reliable rows and columns.
Yes. Open the TXT file, verify its encoding and separator in the preview, then export it with comma selected as the CSV delimiter.
Paste the table rows copied from a spreadsheet or report, confirm that tabs separate the columns, check the header and preview, then download the result as CSV.
No. Pasted text and local files are parsed in your browser and are not sent to an application server.
